Joke Gift For A 10th Yr Anniversarry

My bestfriends will be celebrating their 10th year Anniv. In a few weeks and we`re throwing them a surprise party as well. I want to to give them a "joke" gift for the both of them, but I don`t know what...
If any of you have any suggestions, i`d greatly appreciate them...this couple is also a "joker" couple too,...
