I don't believe in reincarnation, and I didn't believe in it when I was a hamster.

You really don't want to kiss a hamster.

I used to believe in reincarnation, but that was long ago, in another life

I don't wanna talk to you no more, you empty headed animal food trough wiper! I fart in your general direction! You mother was a hamster and your father smelt of elderberries!

I believe in reincarnation of the soul.

I believe in reincarnation, and I believe I've lived quite a few lives.
