All right, this really isn’t a “yo mama” joke you can use in other situations, but it was the high point of my high school experience.
When I ran cross country from eighth grade to junior year (got mono senior year), yo mama jokes were the funniest things in the world to the team, especially Jeremy and Scott, who were both a year older than me and we constantly ragging on each other’s moms.
Ok–last meet of the season, my junior year, we’re driving back from some high school an hour away (it was the regionals, in case anyone cares–only three kids from my school were going on to state. I was not among them, but I did get my personal best time at that meet–22:37).
It’s fairly late at night, and we’ve been taking our times coming home. I’m in a car with Jeremy, Scott, my friend Laura, and this boy Neal who was madly in love with either Laura or me.
Laura says, “Hey–I’m hungry. Can we stop somewhere to eat?”
Jeremy, who is driving, asks, “Sure–but where can we go that’s cheap and open all right?”
“Besides your mother’s legs!!??” I yell out, not even thinking before I spoke. The response just came to me, and I had to say it.
There was a pause of about ten seconds before Scott and Jeremy collapse into laughter. I had earned their respect that day. I just saw one of them three nights ago, and he introduced me as, “Kristen, the crown princess of yo mama jokes.”
It truly was the high point of my life.
