Takes a look at god-checker:
*ahem*
YARA-MA-YHA-WHO: Very nasty little vampire. He looks like a small red man with an enormous head, but has no teeth and octopus-like suckers for fingers. If you ever sit beneath an Australian fig tree, be very careful. YARA-MA-YHA-WHO is likely to jump on top of you and suck all your blood out. And then eat you.
Strangely enough, as soon as his food has gone down, he vomits it back up again. His victims are thus miraculously reborn, albeit slightly shorter.
Should he happen to catch the same person repeatedly, the unfortunate regurgitatee will get smaller and redder each time, eventually becoming a YARA-MA-YHA-WHO themselves.
Not necessarily a GOD, persay, but still funny.
On the topic of Faen gods, Henry, I recall quite a few funny ones from a short-lived Au campaign:
Messava - Goddess of Carpet Stains
Atlia - God of Pork Chop Sandwiches
Nweehaaa - God of swinging over wide chasms on vines
Mattage - Goddess of Sukling Around All Depressing-Like
Theagadabangbang - God of Faen-Turned-Mojh with Hemophelia
