* Played with in the "Thanksgiving" trailer in ''Film/{{Grindhouse}}'', when two small-town detectives are investigating a murder scene amid the titular holiday parade. And by "investigating a murder scene" we mean, "The headless body is right there and the blood ''is still leaking out of it''".

* Dumbledore in ''Film/HarryPotterAndTheHalfBloodPrince''. "Dragon blood."
* ''Film/LoadedWeapon1'' has an example where it's ketchup, given it's a parody.

* The 2001 obscure Nickelodeon movie, ''Film/SnowDay'', had the elementary students try to derail the snowplow man's efforts to remove the snow from the streets since it will reopen their snowed-in school. One of their less successful methods was having one of the students lie in the middle of the street in wait of the snowplow man with ketchup on his shirt pretending to be unconscious. Bemused, the snowplow man simply stands next to the boy, dipping his frenchfries in the ketchup and eating them.

* ''Series/TheXFiles'', episode "Revelations": Mulder dabs his finger in "blood" and '''licks''' it. He promptly informs Scully that it has too much sugar. The look on Scully's face...

* ''Series/Bunkd'': In "Inn Trouble", after seeing Finn licking the "dirt" off of his arm, Gwen reaches over and puts her finger into the "blood" on his elbow and tastes it, recognizing it as raspberry jam. Lampshaded by Destiny who asked her what if it had been blood.

-->''Young Donald:'' Yep- strawberry jam!
-->''Dewey:'' What would you have done if it weren't?

* In a sketch in ''Series/HorribleHistories'', Viking Paramedics ''know'' it's blood already. They taste it because they believe they can figure out what's wrong with the patient by doing so. [[RealityEnsues They can't]]. This sketch is accompanied by the most, if not the only, truly serious DontTryThisAtHome warning on the show.

-->'''Cop 1:''' (Touches, then tastes) "It's blood." '''Cop 2:''' "Son-of-a-bitch!"

* Gimli tops it by tasting the orc blood in Peter Jackson's rendition of ''Film/TheLordOfTheRings''. While this raises the question of how he even knows the difference to begin with, the fact that he immediately spits it out in disgust suggests he's familiar with its repulsive taste.

* ''Series/DoctorWho'': In [[Recap/DoctorWho2005CSTheChristmasInvasion "The Christmas Invasion"]], the Doctor does this. He then tastes the blood and identifies it as "A-positive, with just a hint of iron" (Although his BizarreAlienBiology could let him do this).

* ''ComicBook/CaballisticsInc''': During the mission at the Luddgate studio, Hannah tastes some of the blood the team finds all over the floor. It's not real, being merely KensingtonGore, but the blood itself is drippling down from mid-air.
* In a Creator/MarvelComics {{Dracula}} story set during World War II, Dracula identifies a bloodstain as "gypsy blood" this way. Well, he is a [[JustifiedTrope vampire]]... (Nazi troops were killing Roma. The Roma in Transylvania are protected by Dracula. Bad Move.)

* In an episode of ''Series/{{Beastmaster}}'', Dar sees a spilled blue fluid and dips the tip of his spear in it so he can examine it without having to crouch. It turns out to be unicorn blood, and the blood on the spear makes it child's play for an EvilChancellor to frame him for attacking the unicorns.
