Also, the series has [[Narm/SonicTheHedgehog a page]] for being [[{{Narm}} unintentionally hilarious]].

* Beating ''VideoGame/SonicTheHedgehog1'' with all Chaos Emeralds results in an ending in which Robotnik [[AgitatedItemStomping angrily stomps on the "END" logo]] repeatedly.
* The very manuals of the Classic Sonic games often warned of the dangers of going too fast, refering to certain bugs/quirks that result in trapping the player as "Dr Robotnik's diabolical speed traps". Yes. It's one of the most amusing ways of reinforcing the Doctor's character while handwaving some of the, ah, technical difficulties that arise from Sonic actually being fast enough to literally run headlong into minor gamebreaking bugs.
* Shadow's LV. 2 attack in the first SonicRiders involves him roundhouse kicking anyone he comes close to... yes, even [[TokenMiniMoe Cream]]. Try it sometime.
* The opponent related throws in ''VideoGame/SonicTheFighters''.
** For Amy's, the character takes her hammer and smacks her over the head with it.
*** The way all the characters' heads look when flattened are hilarious.
** The character yanks back Espio's tongue and releases it, causing it to smack him in his face like a rubber band.
*** Depicted in fanart [[ here]].
** The character steals Fang's popgun from his holster, causing him to panic before shooting him in the face with it.
** The character takes a bomb from Bean, [[FeedItABomb shoves it in his mouth]], and ducks in cover for a few seconds while Bean makes hilarious faces and the bomb explodes.
** Several of the attacks in general are funny. The game is practically ''Sonic the Hedgehog'' [[XMeetsY meets]] ''WesternAnimation/LooneyTunes'' meets ''VideoGame/VirtuaFighter''.
* ''VideoGame/SonicTheHedgehog2'' had a promotion where you could receive it for free with the purchase of any Sega Genesis that came with ''Sonic 1''. [[ The commercial]], however, [[AdvertisingTropes didn't stop there]].
* Meta example: Locked-on ''[[VideoGame/Sonic3AndKnuckles Sonic & Knuckles]]'' cartridge [[ x 30]] = glitchy craziness.
* In Sonic 3 and Knuckles when you enter Mushroom Hill Zone after finishing Launch Base, Sonic and Tails or just Tails fly in and land. Knuckles on the other hand falls from the sky and his expression is hilarious.
* [[ The official twitter account of the series]] was fairly standard as far as corporate accounts go. [[ Then they got a new community manager.]]
* In all of the 16-bit games, the expression on Robotnik's face whenever you hit him is priceless and makes one grateful that he [[RecurringBoss shows up in every level]]. His AsideGlance when he enters play or hits you is also pretty funny.
* Also in the 16-bit games, if you're playing as Sonic with the AI controlling Tails, any time Tails delivers the final blow to Robotnik's machine in a boss fight.
* For April Fools' Day 2016, the Sonic social media guys gave the world [[ Big's Big Fishing Adventure 3]].
* From the GameMod (of ''Sonic 1'' and ''2'') ''Sonic Classic Heroes'', you can switch between Sonic, Tails, and Knuckles if playing on Team Hero. In the infamous Labyrinth Zone boss, if you get the idea to swim your way to the top as Tails, [[WhatTheHellHero leaving Sonic and Knuckles to drown]], what will happen instead most of the time is one or both of them will desperately grab onto the swimming Tails hoping to escape. But Tails can't carry anyone while swimming, so instead he will tire out instantly and fall down with the other two. Possibly the funniest unintentional use of VideoGameCrueltyPunishment.
