Ralf: I'm very bad at getting up in the mornings, most evenings I go out to play football, so to spend a night in I would have to be injured or the match would have to be canceled.
Ralf: I check my emails about once every six months so I open them, reply to a few, but then get bored quickly. I then go on to the internet and start looking for pornography and download as much of that as possible. I leave the computer on all night but, wow, what a collection!
Ralf: I once had to make my friend a cup of tea and, for a hilarious joke, I didn't put any sugar in - they've never forgiven me.
