Can't beat Half Man Half Biscuit for amusing lyrics.
With song titles like "Ninety nine percent of gargoyles look like Bob Todd", "Dickie Davis eyes" and "Trumpton Riots" you can't really go wrong.
Note to non-UK resident readers:
Bob Todd - the ugly big bald guy from the Benny Hill Show
Dickie Davis - dapper sports journalist from the late 70s/80s
