High School Musical was a small screen phenomenon when it debuted on Disney Channel back in 2006, and it quickly became the channel's most successful original movie to date. High School Musical was followed up by High School Musical 2 in 2007 on Disney Channel and then High School Musical 3: Senior Year on the big screen in 2008. The franchise is responsible for elevating young Zac Efron into stardom, and he wouldn't be a household name nowadays if not for singing and dancing as Troy Bolton on the Disney Channel. Efron recently celebrated his birthday, and his on-screen HSM dad shared a very special (and pretty hilarious) message:

???? HAPPY BIRTHDAY SON!! ???? From your father, coach & biggest fan. Can NOT Believe you’re 30 years old bro!! Where has the time gone?? 30!!!!??? I think that’s how old I was when we shot HSM1 and to think that now we are just about the same age!! (I’m pretty sure that’s how that works. Right?). Crazy man!! Time flies!! So proud and happy to see you go on to do so many great films and leaving me in the dust to live in my glory days of keeping the HSM fans / Wildcats fed with occasional love notes and throwbacks in the form of memes and my struggling identity crisis when I forget and wake up thinking I’m still coaching the East High Wildcats and Darbus is still the biggest conflict in my life. I hate her, btw. I try and just laugh through my tears... but it’s hard when she has literally ruined everything in my life. This pic is a throwback to #HSM2 premier when I didn’t wear this shirt but man I wish I would have. Now here we are all these years later... just a couple of regular ole leading men, just about the same age that the entire world refers to as the two biggest heart throbs on earth. Crazy. It’s a burden to carry... but I’m glad it’s you I get to take this journey with. People don’t understand our struggle. I call it the “Bolton Curse” and you have to just accept the lifetime of love and admiration that’s constantly thrown at you. I know it gets old. Trust me. Hang in there man!! Zac I’m super proud of you and wishing you all the best on this special day. Can’t wait to see “The Greatest Showman”!! Love ya buddy!! ( Thanks for the shirt @rowlandbb ) ???????? #zacefron #troybolton #coachbolton #boltoncurse #hsm

A post shared by Bart Johnson (@bart_johnson) on

Bart Johnson shared the post on his Instagram account, and it's pretty fun to read. I'm guessing he's not the only one surprised by the fact that Zac Efron is already 30-years-old. It seems like only yesterday he was trying to balance his loves of basketball and musical theater to peppy montages! As Coach Bolton, Bart Johnson disapproved of all the singing and dancing when there was basketball to be played, and Johnson amusingly made sure to mention Miss Darbus in his post.

As High School Musical fans will remember, Coach Bolton and Miss Darbus were the nemeses of the East High faculty. Bolton wanted nothing more than for his basketball stars to get their heads in the game, but Miss Darbus wasn't happy to give them special treatment. Both probably would have been fine with sticking to the status quo if not for Troy and Gabriella breaking free. Coach Bolton and Miss Darbus did come to terms with each other, but some wounds clearly never heal.

I definitely got a laugh out of the "Bolton Curse" that Bart Johnson mentioned in his post. Apparently Zac Efron and Bart Johnson are both dealing with the complications of being big showbiz heartthrobs. Good for Johnson for powering through and suffering in silence until this point! The only way this photo and message could be any better is if Efron responded with a selfie showing off a t-shirt with Bart Johnson's face.

We probably shouldn't hold our breath on that one, although stranger things have happened. Who could have guessed that the kid from that made-for-TV musical would reach the showbiz heights Efron has over the years? Other members of the cast aren't doing too badly either. Vanessa Hudgens even revisited her TV musical days last year with a memorable performance as Rizzo in Grease Live!

If you now feel the need for a trip down musical memory lane, High School Musical and High School Musical 2 are both available streaming on Netflix.
