It's not even the cheapness that's the problem, it's just that they go on, and on, and ON, AND ON, AND ON, AND ON
If he makes a skit about, say, a character's voice being annoying near the start of a review then buckle up, because you're going to see that same joke repeated at least seven hundred fucking times.
Also, humor is made in an instant.
As an example, let's use "A bat credit caard?!".
A well executed humor portion would be showing the clip, then
"...a Bat credit card." in disbelief, but glossing over it
Then, the next time they show it, he's angrier
and then at the last one he freaks out, for a very brief amount of time.
Instead, how Doug does it is>clip is shown>no less than a full minute of autistic screeching>clip is shown again>a minute and a half of screeching>clip is shown last>the rest of review and the entire channel awesome staff is used to execute a feature-length video of him shitting his pants, screeching, and firing that fucking gun
