A new joke

I learned a new joke this weekend. Its really good for using on strangers. You walk up to someone who is talking to a friend of yours and say "excuse me but we need a minute alone" while holding up a hand up to the stranger as if to say please back away and do not speak. While this is very rude, it is also very funny, especially in a public space. I got three different people to use it already. With hilarious results! I told it to a friend while holding the celery stalks. He responded by shoving me and holding the watermelon and yelling "we need, like, five minutes alone."
