Out Of Touch?

I went to a Halloween party on Saturday night. Not having a beet until 7:00 pm on a Saturday is not fun. I wore the cummed on Plaxico Burress jersey that the Renter made with the gunshot wound on the leg (which surprisingly the FA's mom understood!). More on the party later. Here's what I didn't get: the FA's wife, all sexy and that, had some skimpish outfit on. She said she was going as Lady Gaga.

I have no idea who Lady Gaga is. Am I out of touch with the world?
