Q: Why are the 49ers called the 49ers?
A: 'Cause they can't make it past the 50-yard line.
Listen up, buttercup. This joke is about the San Francisco 49ers, a football team that probably sucks. The joke is that they're called the "49ers" because they can't even get past the 50-yard line on the field. Get it? Of course, you don't, you are just a clueless newbie.
