NOW YA SEE ME NOW YA DONT! *BIG GRINS*
You are most like...The Cheshire Cat.

Generally you are smart funny and entertaining but when you get stoned you change completely. Your jokes get irritating and you just sit there and grin like an idiot. Will often disappear for long amounts of time and returns again at random to proclaim... I was in the kitchen getting food!

Damn, that shit is accurate to a scary level.
