A large man walked into a public restroom where a small man was peeing. The big guy said to the little one, 'Excuse me for noticing, but you have a very large dick. How did it get that way?' The little guy said, 'Well, I'm a leprechaun, I wished it upon myself.' The big guy said, 'Wow, could you wish it upon me?' The little guy said, 'Sure, but only if you let me give it to you from behind for 5 minutes. The big guy agreed. After it was all over the big guy said, 'I can't believe I let you do that.' The little guy said, 'I can't believe you thought I was a leprechaun?'.
