Once a Wildcat, always a Wildcat. That quote from Troy Bolton's graduation speech in High School Musical 3: Senior Year didn't fall on deaf ears, because Corbin Bleu's bachelor party over the weekend featured fellow HSM bro, Lucas Grabeel.

Celebrating his soon-to-be marriage to Sasha Clements, Bleu partied it up in true Hangover-style: in Las Vegas.

For starters, Bleu's squad knew how to make a guy feel special.

Hanging out at TAO Las Vegas nightclub, Bleu described the whole thing as an "epic intro."

They went golfing, but no word on who won. 👀

But apparently, they didn't do the whole "let's walk around in the heat for 18 holes and call it a day" kind of golf. Instead, Bleu said, "The balls have little tracking devices in them and you hit them into targets!" That sounds like more work, TBH.

Although based on this video, I'm gonna assume the winner was Bleu.

Later, the guys ate inside Caesar's Palace — though not the real Caesar's Palace.

The actor and singer also shook his groove thing after getting pulled onstage during the Cirque Du Soleil Zumanity show.

And what party would be complete without Zedd living it up at the XS Nightclub?

Seriously, once a Wildcat, always a Wildcat.
