The University of Minnesota posted video of a guy on the "kiss cam" at a hockey game on Valentine's Day.  But he wouldn't kiss the woman he was sitting with . . . because it was his SISTER.

 

 

And we know because he came prepared, and held up a sign that said, "My Sister" with an arrow pointing to her.  (Search for "Guy Pulls Out Sign on Gophers Kiss Cam."  For some reason, there's no audio.  He holds up the sign at :26.)
