i find it hard to gauge the funnies because all metal has me in hysterics once i've had a few drinks.
there's nothin' funny 'bout MANOWAR!
you just don't get it, man. it's so evil and tr00 that you resort to laughter to protect your frail soul!
STRONG TRUTH.

Goblin Cock - are they metal?
Demons and Wizards!
ROUGH SILK!
Sounds like the band formed after The New Originals.
Budgie is pretty funny metal name, but I gather they're a bit more prog. Cradle of Filth makes me laugh too.
Flowing Tears and Withered Flowers (german goth metal)
Scrotum Grinder
Bestial Warlust
There was this semi-parody metal band called LAWNMOWER DETH on Earache in the 90s.
Song titles such as 'Satan's Trampoline', 'Seventh Church Of The Apocalyptic Lawnmower' and 'Sorrow (So Dark, So Scared)' kind of giving the game away to fabulous effect!
CONTRIVE is the best, it's so...honest.
Fall of the Leafe
Lucid Dementia
A friend of mine was in a local band called Furious George. The same friend also came up with a name for a silly glam metal band - Sham Pain. Awesome funny name!
