I'm starting to get the feeling these are staged -- he clearly gets "pranked" all the time but each time we get a "why have you got a camera" and all the usual stuff.
Reactions seem a bit too unrealistic, hardly suspects anything despite the camera the entire time, asking the store clerk footage mysteriously not there, pretty organised looking ending and conclusion.
I think I used up all of my suspension of disbelief.
Knowing it's not real stops me from laughing
By now he should know that whenever something goes bad and his brother is filming, it's fault
"This is an incredibly hot and dangerous pepper, so I'm going to use it to harm my friend"
I seriously hope he breaks your teeth and then calls it a prank.
