Just some more examples:

Warfare supposedly has a big ass chute where if someone falls inside of it, they're taken all the way to Mexico. While the opening of the chute itself is visible, and we do show people getting pushed inside, we don't show them coming out on the other end. We just let the audience assume that it either really does exist or it's load of bullshit.

Another example is Stevie Tyler morphing into Gary. We can't really have him transform into the incredible hulk mid-match in plain view, but what we can do is have him go under the ring and come back out as a different person. Referee is stunned, checks under the ring, can't find Stevie, and so he can only assume that Stevie IS Gary since he knows Stevie's background.
