He was also a bastard on Popworld which makes him great.

I remember the story he told when he was a guest on Buzzcocks.

One time on Popworld they had S Club Juniors on, y'know, the midget freak version of the already bad S Club. Well, it was the time of the month for one of the girls, her first in fact, and all the crew on the show were being very supportive and so on. Amstell decided to show his solidarity with this girl and the problems she was suffering, so he introduced the group in a heartwarming manner :

"And now, we have S Club Juniors, probably my favourite band ever. Period."
