12. Jack Black

“We passed him walking down a street in LA. My daughter says “I swear that’s Jack Black!” We doubted her so she yells (he’s about 10 yards away) “hey are you Jack Black?”
He stops, turns around and says “I am.” Then he walked back up to our group, took a picture with my kids, chatted with my husband about Judas Priest (my hubby was wearing their latest tour shirt) and signed autographs. I was with a group of six tweens/teens and he engaged every one of them in a conversation.” – jbarinsd
Well, we all know Jack Black is cool and fun, but walking back to a group after spotting you and chatting away with them is so unexpected!
