You haven't seen a shitty T-shirt until you've turned up at someone else's house and asked to borrow something to sleep in.
I stayed over at my girlfriend's mum's house at the weekend. Here was my choice: either A) the XL 'turquoise dolphin' number...
... or B) the XXXL 'turquoise Destination Florida' design (with the hyper-baggy sleeves).
Because it's always a fucking charity T-shirt.
