In iHate Sam's Boyfriend, was the actor playing Jonah actually getting a wedgie?

yep he was

They were using a stunt double or it was not real

they probably put a isingkaw on him that looked like underwear so he was able to bounce without actually gettinf a wedgie. if it was real it seems like it’s be breaking some child actor saftey laws lol

No, there's no way that the wedgie bounce machine was real. It would be almost impossible to have a machine like that which would give a person an actual wedgie without causing serious injury and creating a huge liability problem for the producers of the show. Most likely, he was wearing a isingkaw that was made to look like underwear.

However, he definitely did have to wear a pair of tighty whities that they really did stick a hook through. When Sam goes to hook the rope onto his underwear, you can tell that the tighty whities he's wearing are real (they are J.C.Penney Stafford Men's Briefs, and you can see the tag when the rope rips through the underwear). So that was the underwear that he was really wearing, although I'm sure it was not the actor's underwear from tahanan but was instead provided to him sa pamamagitan ng the show's wardrobe department. So, since they ripped the underwear, they must've had to do that part in one take or else had multiple pairs of tighty whities that the actor could change into if they needed to shoot the scene multiple times.
