What should i buy my best friend for his wedding gift?

tickets to a sports game

gift card to a sporting goods store ( they sell atheltic equipment and sports stuff)

maybe a mug of his favorite sport, team player, sports player or team

box to put his keys, change, wallet, watch in

maybe some sports bedding

jersey of his favorite sports team or player

pj pants of his favorite sports team or player

new wallet

new watch

pocket watch

slippers or bath robe of his favorite sports team or player

A camera

Oh wait I actually really like the goldfish idea. Get a 30-40 gallon tank and 3 or four fancy goldfish.

give him a honeymoon tickets to his favorite place where he was dying to go with a big box of condom packets (such gift can be given by a best friend to a boy only)

some personalised sporting gear - a bat,gloves,socks

or you could give him an experience day gift,something related to sport:

im sure you could find something in your area,the above is just to illustrate what is out there

get him a really epic football with something special written on it or pictures pasted all over it (pictures like you guys or him and his future wife having a good time and everything)

How about a sports pillow with his favorite team on it.
