As well as all other games in the Mario & Luigi series, if you jump on a spiky or flame covered enemy. Interestingly, Mario & Luigi: Dream Team can have this happen to Dreamy Luigi when you jump on a horde of enemies (half of which have spikes) in the Dream World. Cue half the clones safely bashing enemy heads in and the other half hopping away in pain.
This also happens in the Paper Mario series when you attempt to jump on a spiked enemy without the Spike Shield badge.
Fallout 4 gives new graphics for Knee Capping a Deathclaw. If you cripple their legs, they're reduced to a pathetic crawl, with their tibias jutting a good foot out of their leg. Yikes.
In Knights of the Old Republic, the player encounters a computer console which only outputs in an ancient language. The proper way to deal with it is to talk to it until it understands your language, but one option is to simply kick the computer. Doing so only gives you this:
Console: You kick the computer. Your foot hurts.
When knocking off the manhole cover over King Hippo's belly in the Wii Punch-Out!! game, it lands on his foot, causing him to hop up and down while holding it.
During the boss fight against Zant in The Legend of Zelda: Twilight Princess, at one point he becomes a giant, and in order to defeat him, you must swing the iron ball and chain into his foot.

Die Hard for the NES includes a separate health meter for John's feet, representing the injuries he sustained through the course of the film.
Doom, the Roguelike want to tromp through acid or lava? Better get some good boots or else your poor Doomguy will cry out in pain with every step. Or if you can't find those, you could always just tromp through the stuff barefoot. That works too apparently.
Kid Icarus: Uprising has a boss, the Great Reaper, that is fought in a two story battlefield. Each floor has a corresponding weak point, his head and his toes.
The Scout could scatter caltrops behind him to hinder pursuit. If stepped on, they slightly damage you to the point they can kill you. They also give you the "broken feet" debuff, which slows you down until cured by the Medic.
The Sniper can do the same thing by shooting an opponent's legs.
One possible news story in Tomodachi Life has a Mii stub their toe on an item while trying to get the phone. Gets ridiculous if the item in question is something unusual, like a travel ticket.
DC Universe Online: One of Harley Quinn's attacks during her boss fight is to run at the player while smashing her wooden mallet repeatedly on the ground in front of her. Eventually she will bring the hammer down on her own foot, which results in the usual reaction and leaves her open to attack.
Yakuza 0 has a non-comedic example: while subjecting Tachibana to Cold-Blooded Torture to get Makoto's location, Yoneda smashes Tachibana's toes with a sledgehammer. Tachibana is obviously in immense pain, but continues telling his torturers jack..
During the exam portion, Edel decides to demonstrate the toughness of a particular puni... by kicking it.
Edel: As you can see, this is a very tough puni... enough to make my foot hurt.
Firis: (Wow... That sounded really painful...)
In the post-game, Firis decides to go journeying again and visits her parents to tell them, only for her father Lukas to incorrectly conclude that she's about to tell them she's getting married and try to forbid it because she's too young. After she explains what she's really about, both are fine with it, having honestly expected her to come to them with this a lot sooner. They say that they're fine with her doing whatever she wants...
Lukas: That is, except for getting married... Owwww! Nicola! Don't step on my foot!
In the Genesis version of the Aladdin video game, guards running across hot coals will grab their feet and hop in pain, leaving them open to attack from Aladdin. Aladdin himself can land on the coals without damage, but flames will almost immediately sprout up when he does, meaning he has to move quick or take damage.
