Season 4, Episode 19: "The Implant"

Their last date they were on the couch...

-...but she was on his wrong side. -Wrong side?

Yeah, she was on his right side. He can't make a move with his left hand.

-He can't go left? -No.

I'm lefty. Can't go right.

What about women? They go left or right?

No, we just play defense.
