The cuts are there for two reasons: One, to immediately identify this as a parody of prank videos, and not a real prank video. I wasn't trying to fool anyone into thinking it's real, but the problem is, some people wouldn't be able to tell the difference (that's also why the lightning looks so over-the-top fake)
The second, and more important reason: I didn't want to ruin my toaster. Lol.... I actually threw in a tub of baby wipes, and then tracked an image of that toaster over it.
