All 56 kg's of man

Had a friend over for dinner tonight. He's skinny to say the least, but the funniest was when a woman friend of mine joined in and realized that he weighs less than she. The look on her face was unbeatable. "You weigh only 56 kg's?", and I could see her mind going "oh fuck, I weigh more than that". HAHAHAHAHAHA. Funny thing is that she's rather skinny herself, but perhaps her rather sizable arse makes up for the weight...
