Tina Fey could play charades with us any day. The 48-year-old comedian stopped by The Tonight Show on Thursday and participated in a similar version of the game called "What's Behind Me?" In the clip, Tina and host Jimmy Fallon take turns giving each other just enough clues to guess what (very strange) scenes are taking place behind them. Without giving too much away, we'll only tell you to look out for a cameo from E.T. the Extra-Terrestrial. Watch the funny moment above, then check out what Tina says is her favorite quote from Mean Girls. Seriously, someone get Tina and Jimmy in a buddy comedy ASAP!
