Probably the happiest way to die you can possibly think of, not counting death by orgasm.

I try to use this phrase in conversation at least once a week.  For example:

You: Man, that's a horrible way to die...with all the scarring and fire and explosions and whatnot.
Me: Yeah, I'd much rather be licked to death by kittens.

Or...

Me: So, how do you feel about world peace?
You: Well, it's better than a kick in the teeth.
Me: Ah, but is it better than being licked to death by kittens?
 

With some help and guidance, you too can be licked to death by kittens.
