The following joke is potentially offensive to animal lovers, and basically anyone who cannot stand politically incorrect jokes.
A sadist, masochist, bestialist and a necrophile were having a discussion. The bestialist said, "I love cats." The sadist said "I love abusing cats." The necrophile said "I love abusing dead cats." They all then turned to look at the masochist.
The masochist went "Meow!"
