Dip Circle Puns

My fiancee knocked on to the floor at a friends house, a single slice cake we had got from Smith's; comes packaged in a small, square plastic container, and was still in the container when it hit the carpet. I still proceeded to give her a hard time saying she did it on purpose, etc. As she reached over to pick it up she accidentally dipped her shirt on to the top of a caramel covered brownie she was eating. She sat back up and noticed the caramel circle covering the nipple of her shirt, and without second thought cries, "Aww man, caramel's a bitch."
