I was in the kitchen of this girls house last night and I went to get a drink when I smelled something, I said to her "I think your plumbing is broken" which she replied "I don't smell anything". Only for me to find out later that night that it was her you know what that stunk. Therefore I ran out the house sayin "sewage sink".

Tim: Zack, is that your exgirlfriend?
Zack: No, she's an expotential. We never actually dated...
