The simulated physics for weapons, projectiles and the titular worms can result in quite a few Hoist by Their Own Petard moments, but more particularly is when a player opts for Complexity Addiction with some variety of weapons to try to kill one or even several worms at once — only for everything to fall apart and potentially only kill themselves with it, when the Boring, but Practical solutions would've solved the problem in an instant.
Try throwing a grenade towards a bundle of worms in Reloaded and they all start screaming. Not a continuous one, either, they just scream multiple times with a blank expression and in the most hilarious way ever.
The fact that some of the most powerful weapons are... unorthodox to say the least. Exploding sheep, concrete donkeys, flying sheep, letter bombs, old women, flaming sheep, carpet bombs, swimming sheep. The more absurd the weapon is, the more damage it can do.
Worms 4: Mayhem adds in some really funny Animated Outtakes. Some highlights include a worm refusing to get into a proper wizard costume, car prop trouble, a worm getting blown up in a mine, a worm's audition going badly, and some Camera Abuse in the Wild West.
Ultimate Mayhem adds in some (this time real) Hilarious Outtakes of its own with the amazing flubs of Guy Harris.
Narrator: Those crates may contain something… Useful. I nearly said awful, but I've no idea what's in them, so how would I know? Narrator: They wish to introduce you to defeat. And the knees. And the hips. And the hands. And the head. And the elbows. And the face, and the eyes, and the nose. Right! Narrator: Bat Ali Balloon's... Boodibudoodoodedoodoons. Bat Ali Baboon's goons into the light. You try saying that! Bet Ali Baboon's goons into... What? No... Bat Ali Balloon's. Balloon's? Whose he? Narrator: (Toilet flush can be heard offscreen) Someone's havin' a dump, you can hear the flush… Bear with.
Narrator: Yes, we meant 'skillz' and not 'skills', cos we're... 33t. What? Because we're what? 33… I don't know what that means… L33T of course! With two threes instead of two E's!
Adding to the hilarity are the bloopers being portrayed in-game with a worm in the recording booth representing Harris and the audio director and the technician getting annoyed but sometimes laughing as well.
When a worm dies, assuming they didn't do so of being thrown off the arena or falling into the pit, they explode. The explosion causes damage. If they're surrounded by other low-health worms, this can result in multiple worms dying in a row. Even more hilarious is if the explosion propels a mine into another worm (or vice versa), or blows up a supply crate.
