Mad Snail Disease

From SpongeBob SquarePants

Mad Snail Disease is a mythological disease that was believed that snails could be afflicted with. Dr. Gill Gilliam appeared to be the only one in Bikini Bottom who could confirm that the disease is a myth. Some symptoms include ticklish ribs, zombie like behavior, loss of balance and "A few other symptoms". The first known "victim" is Squidward Tentacles.

[edit] Latest "outbreak"

In the episode Once Bitten, Squidward gets bitten by Gary (only because Gary slithered over Squidward's sharp wooden fences and gets one stuck in his foot). When Patrick sees Squidward getting bitten by Gary, he tells Squidward that Gary has "Mad Snail Diease". SpongeBob tries to take Gary to Snail Care, but Gary escapes and bites nearly every Bikini Bottomite until Dr. Gill Gilliam tells Bikini Bottom that Mad Snail Diease is just a common bitch.
