Joke stolen from: JuSt JoKiN' byTAC

Occasionally at the restaurant where I work there are extra desserts, and the staff are given some to take home. Once I brought home two pieces of cheesecake for my son and daughter. Katie had a piece that evening.

The next day her older brother found her watching TV and eating more cheesecake. "Are you eating my cheesecake?" he demanded.

"Oh, no," she replied sweetly, "I ate yours yesterday."
