One prank you could play on the groom is to fill the groomsmen's pocket with a few loose rocks when they aren't looking.  When they take their pockets out later, they’ll find the rocks and could cause them embarrassment throughout the rest of the day! You could also fill their car with balloons or stick post-it notes to their backs with hilarious messages during the ceremony. It’ll create plenty of laughing and make for lots of memories during what should be a happy day.

Some practical jokes that can be played on a groom include: having some fake snow blown out of balloons when he opens the doors for the ceremony; hiding a chicken or some other jokey prop in his car and surprise him with it when he gets to the reception; slipping something gross like bright-coloured jellybeans onto his seat while he's waiting to give a speech; rigging up a microphone so that it turns up every time he tries to answer a question - loudly playing along to his own jokes! 

Other potential ideas include: filling an antique clock with expanding foam and setting it going before his best man's speech; placing several large, real-looking insects on top of the cake just as he cuts into it; pinning pictures of him on public display (preferably not nude!) around town before the wedding day. These are just some suggestions - feel free to get creative!
