A blonde calling her mom:

"Hi Mom, how are you?"
"Hi Buffy, where are you? I thought you were with your father at the Ace Hardware store."
"Yeah, we were in the beginning, but I got arrested, and they've let me make one phone call"
"What happened?"
"Oh, I punched this African-American woman."
"What? Why on Earth did you do that ?
"Well it wasn't my fault . . . Dad told me to find a Black & Decker."
