Talking of best friends of the opposite sex, mine just had me on a complete wind up that he was on a golf course on his own, there was a really fit girl playing in front of him, he accidentally knocked his ball next to her, they ended up playing together and then she gave him a BJ in his car, which happened 2 more times.
When he took her for dinner she said she was a guy. I fell for every word. I felt all shades of bad for laughing.
He just included a bit of me in a new tattoo though so I forgave him.
