#1 I visited my identical twin brother at his college where a lot of his floor didn t know he was a twin. That night he had some people over in his apartment and I hid in the bedroom.
Note, he has a beard and I don t.
While they were hanging out (and me hiding), he announces to the group that he s tired of his beard and is gonna shave it off, so he escapes to the bedroom where I m hiding as if to shave. We switch clothes and I walk back out to the group with my bare face. Everyone takes note and, while it s generally an unusual thing to do at a party, nobody thinks much of it.
