Need a favour

I have a good friend here in Toronto who is a Sheffield United fan. We are doing a 10K race in May and then going to a gig that night, so we have made a bet that whoever loses the race has to wear the other team's shirt to the gig. He's 5'10" and probably 220, so none of my shirts will fit. Any of you boys willing to lend me a shirt please? I'm over in a couple of weeks at the Arsenal game and can meet you in Notts or London, and will mail it back after the race. I don't want to have to buy a shirt just for this, and I'm definitely going to need one because I'm absolutely not losing. Age and condition of it doesn't matter and I promise I'll wash the Yorkshire stench out before returning it (even though he's from Essex).

That's basically me give or take an extra 1" an an extra 6lbs, happy to lend one. If you want Scargill was a wanker printed on the back let me know.
