Recently, Wells Fargo took over Wachovia. My daughter's Joke on that takeover is: Well I guess Wells Fargo is going to wachovia money. (read and pronounce wachovia like this: watch ovia)
She told that joke to us, (me and her brother) but then her brother used it in front of a cashier and got a laugh. She felt like He was stealing her Jokes and we had to discuss plagiarism/ and rights to jokes etc.
