We sent to a murder mystery birthday party which was 80's themed. It was fun, but I didn't get the murder right (I actually thought it was Greg...even though he was my character's husband.) He took the getting into character seriously. His character was apparently supposed to be kinda a douche (we were the prom king and queen, actually), and he mimicked Will Arnett's voice for like 36 hours (including long after the party was over). At one point, Felicity said "you sound like Batman from Lego Movie" which really made us laugh, because he's played by Will Arnett.
