Blue Man Group

Early in the history of the group, the members would speak with audiences after the show while still in makeup, answering questions, signing autographs, and talking about the show. Eventually, however, it was decided that cast members would stay in character at all times while in makeup, meaning after shows they would still not speak to audience members, and the only "autograph" they would sign would be a smudge of blue paint. When shown a "new" piece of technology, such as a cell phone or even an old pair of binoculars, they will simply stare at it in wonder.
