Here's a couple of fun cartoons about invented religions. Warning, they are not safe for work.
If after watching this cartoon a Scientologist invites you in for auditing procedure R2-45, do decline the invitation:
"R2-45 - an enormously effective process for exteriorization, but its use is frowned upon by this society at this time."
-- L. Ron Hubbard, The Creation of Human Ability - A Handbook of Scientology
In Scientology to exteriorize is to die.
And of course we also have YAAFM: Muslims.
And we all know how Muslims are.
I have to go to work now, bye.
