Funny Bar Stories

I was at my favorite piano bar and the two following weird things happened.

1) A dude did a certain 1930's hand gesture during Frank Sinatra's "My Way". (I can't mention it due to Godwin's law).

2) There were old people (over 60) when the pianist performed a certain Justin Timberlake/Andy Samberg song.

Why does weird stuff always happen when I'm around?
