Do you ever laugh at things you shouldn't? For example?

Pedophiles getting LWOP.

Idiots bungee jumping and the cord breaks.

Cheaters getting caught and hit upside the head hard.

Rooster's fart jokes!  I just can't help it!

I laugh when people are criticizing someone else's spelling and they misspell their complaint.

yes when these punk gangsters get cuffed and stuffed

child molesters get beatup

I used to laugh automatically out of control when someone start to be silly at the classroom, i shouldn't have! But sometimes you can't control. Things happens fast and it's funny!

You never know when you may feel a laugh coming on and you can't stop it though you wish you could. Once my little brother felt moved to be baptised at the local baptist church in the 1960s where he attended both on Sundays & through the boy scouts. This involved of course baptism by immersion, which was new to me and our mom & we both sat near the back.  We had of course been prepared for what to expect, but not for how silly the splashing sounds of the water through the pastor's microphone would strike us. I unfortunately started to snicker through my nose like a series of quiet sniffs, and it grew and I tried to make it sound like a coughing fit, but Mom was by now laughing with tears we somehow left the sanctuary before we burst into laughter outdoors.  We regained our composure and slipped back during the next hymn and afterwards it was as though nobody had taken notice or our bad behavior. On the contrary they embraced us and my Brother like royalty.
Later I attended a baptist university and graduated from there with a B.A. In Visual Art..

There are some really cringe-worthy jokes on Family Guy that make me laugh. This one always gets me:

I laugh in the privacy of my own bedroom.
