Hawhey - what about the first ep of series 2?
With the immortal phrase "Garlic Bread - it's the future, I've tasted it" and Jim Bowen in a Wig, and Jerry singing "Come and get your black bin bags" in Asda to the Men in Black tune.
(Actually if I'm honest, my fave was the Keith Lard one from Series 1, just for the aeorbics scene :roll: )
