So, today...
Strangely, the things there actually seem like the kind of things you guys would do. I could quite easily see Sarah having some eBay fun more than anyone else, John could easily be the most likely to get hold of the forms, I think Silk would find day-glo orange dye on a dog a fun experiment, and Spin just seems to fit right for the TP one.
Somehow though, I don't think Kris would ever be bothered to put in that much effort, not sure whether Meghan would with the glue either.
As for Tim, that's more the prank if he's charged it to my credit card, and no bride turns up...or it's selling me as a Russian bride.
