...bringing everything you need to the coffee table so you dont have to get up from the couch anytime soon. And then finally getting comfy and having to pee grrr.
That happened to me last night!

The only other one I have to add is when you sneeze and it hurts so much you clutch you belly and say "OW" and your DH/DP/coworker looks alarmed and says "Was that a contraction????"
