Going to a funeral and fucking with the body is wayyyyyyyyyy over the line. I'm thinking it's a staged funeral though

The body is fake (could easily have been replaced)

I guess that's the beauty of their format... all their scenes with unaware victims means they can sprinkle in a few scenes staged with actors and the movie audience will be less likely to catch the fakeness.

This gonna be so funny lol..

I remember the drinking episode with bad grandpa in jackass long time ago

what does "i'll just call you cinnamon" means in that context?

Little boy : Whats your stripper stage name
Female : I look like a stripper?
Little boy : I'll just call you cinnamon

It's a stripper name
