Pete: Part 1 (S08E06)

Lister and Rimmer are forced to take on the guards in a basketball game. They manage to sabotage the opposition's half-time juice with 'Boing', the virility enhancement drug. But needless to say, the match is a fiasco and their punishment is two weeks of spud duty. With Bob the Skutter's help, Lister gets hold of a virus which eats potato skins. It also eats clothing and hair. (iTunes)
