Here's how I find friends:

"Hey, I hate small talk, but I love games. Would you like to play a game?"

It's perfect because it's true. And if they say no, then I move on until I find someone I'd actually be excited about being friends with.

If you're looking for puns, here's one:
"Do you like mushrooms? I hope so, 'cause I'm a fun guy." (fun guy=fungi)
