It's all about that left side though...
So that got us thinking...
The answer may certainly surprise you!
Johnny Depp has got his old co-star's back!
The actor makes a very exciting cameo in 21 Jump Street, but the actor had one condition before joining the flick.
Peter DeLuise played Johnny's partner on the TV show and Depp agreed to the cameo when DeLuise was asked to appear as well.
We LUV that Johnny is looking out for his old friends!
Holly Robinson Peete also makes a cameo and there is a tiny homage to another original cast member, Dustin Nguyen.
Richard Grieco left his options open for a sequel, as only season one cast members appeared in this flick.
Are U excited for 21 Jump Street to make a comeback?!
