Überhaupt nicht jugendfrei, dafür sehr lustig. Mein Favoriten:

"My penis is like a Volvo stationwagon. Safe and reliable but kind of boring. A functional tool that will carry the groceries home."

"My vagina is like a Mini Cooper. Small and stylish. Hard to get in, but once you're riding, you have the time of your life. Or maybe it's like a paddy wagon. COS I'M JAILBAIT."

"My penis is like a PT cruiser. It will give you an immune disorder."

"My vagina is like a mint condition '67 Corvette; lots of people want it because it's sleek, stylish, and fast, but they run in terror when they see the price."
