Anyone have a good, harmless wedding prank they can suggest?

My husband's cousin is getting married in a few weeks and it's tradition among the cousins (there are 18 of them) to pull a prank at every wedding. They are harmless pranks done in good fun. We've already done the one where a bunch of people turn in keys to the bride or groom's house. We won't have access to the couple's car or their hotel room. Can anyone suggest anything fun we could do? We wanted to get Chia pets, grow them and give them to the groom, as he is a very hairy guy. But it's hard to find them this time of year.
