Several of Mr. Gray's attempts to get under Jonesy's skin (and their failure) provide laughs.
Mr. Gray: You dreamed him to death!
Henry gleefully trolling several armed soldiers by invoking a Cat Scare with a box of hot dogs.
“Bowser! The remote!”
Jonesy and Duddits distract Mr. Gray by using his hunger against him.
BACON SANDWICH! WITH EXTRA MAYO!

“Listen, Miss Roadkill. You almost got us dead. Say something!”
“Priapic!”
“Priapismic.”
“KISS MY BENDER!”
Shit-weasels. In the same vein as the Ass-Blasters, being a horrifying monster with a completely ridiculous name.
Aside from the nasty looking rash, another sign of infection and a pending shit-weasel erupting out the ass? Burping and farting. It's as ridiculous as it sounds...
Which leads to the above with "Miss Roadkill" letting rip when Henry and Pete ask her to say something. Henry's response is a somewhat deadpan: "I guess that's....how they say hello in these parts..."
Admit it, as horrifying as it is that shit-weasels burrow out of people in a manner that might evoke the thought of a reverse chestburster, the fact that they come out of a person's BUTT simply cannot be taken seriously
