I don't really believe in 'guilty' pleasures as such because I tend to take the view that if you like something, that's fine. It's my spare time, I'll read/watch/play whatever I like.

My favourite food is chocolate-dipped fish and chips served on a steak, with a side order of popcorn, washed down with a vat of strawberry flavoured lard made from the excess body fat of third-world children. I'll confess, I do feel a little guilty about that, but only because I usually leave half of it to avoid ruining my waistline.
