Here are some jokes.
1. A horse walks into a bar. Barkeep goes, "Hey, why the long face?" Horse goes, "I have AIDS. They don't screen as stringently in Tijuana."
2. Why can't you hear a pterodactyl tinkle? Because the 'p' is silent.
3. How many boring people does it take to change a lightbulb? One.
4. What's worse than rewatching your favorite shows as a kid when you grow up, and discovering that they aren't as good as you remember? The Holocaust.
5. What's worse than the Holocaust? Six million Jews.
It's okay, I have a Jewish friend who always tells me that joke is lame, so it's not as offensive as you think. Also I end like every comment with a sentence that doesn't end in a period
