I can find things funny without necessarily bursting into any sort of laughter. Maybe a chuckle.

I totally laugh with the canned laughter. How else would I know what's funny?

I prefer shows without a laughter track, to be honest. They usually have more jokes in and you can actually hear them properly.

Same here.

laughter tracks sound like bacon frying.
i don't laugh often. ever.

even if i find a show very funny, i don't often laugh at it.

canned laughter really annoys me. the shows i'm likely to laugh at all don't have it (for example peep show (sooo amazing), south park (newer ones, i saw the paris hilton one the other night and did laugh my *** off), simpsons..)
