Come on guys, use your imagination
You don't have to go and live the life of the person you're going to visit (i.e, live in a traders garage for 2 days...), the only reason I wanted to spend the weekend with WW in his world is because his world is pretty hectic according to his forum posts so it's got to be interesting..!
But another one I'd do:
I'd hang around with GM, we (read I) would spend most of the first morning laughing about how ridiculously high his car is. Once I get bored of laughing at that, we'd drive straight up north until we hit the sea at which point we would rent a pedalo and see how far we can get towards Ireland before we need to call the sea police. Once we've been rescued we would barter our shoes with the helicopter pilot (who happens to be a crack addict) so that he would drop us off in Ireland.
We'd then hitch a ride with some guy on his horse to the nearest town where we'd get absolutely funked in the Irish pubs, obviously as we're in Ireland we'd have to go scrumping while we're funked. We'd then rent an apartment and try make an apple pie using just our feet and the apples we have scrumped.
Next day, we'd grab some bacon butties and find somewhere to rent a supercar to drive home in.
