INTERESTING POST ON FORUM ABOUT MALE BONDING

What personal act would you perform to complete male bonding ?
Lets say you and a best friend wanted to show each other that you were best of friends and you had to complete some kind of act to prove your friendship for eternity, what would it be?
This is the original post that came from a "straight" guy and you should have heard all the homophobe remarks from other "straight" posters.  So, I wonder what gay/bisexual men would say about this post.   I am thinking about this myself and will respond when I have the right answer.   FOR ONE : it is not to have sex with my friend.
THANKS GUYS ! KEN
