What do you call a cow with 4 legs? (self.tipofmytongue)
submitted February 28, 2017 by georgecena1337
Alright so there are 4 parts to this joke:
What do you call a cow with 4 legs? (A cow)
What do you call a cow with 3 legs? (Tri-tip)
What do you call a cow with 2 legs? (This one has 2 answers: lean meat OR your mom)
What do you call a cow with 1 leg? (Steak/stake)
What do you call a cow with no legs? (Ground beef)
But I could have sworn that the cow with 4 legs had a better/second answer that wasn’t just “A cow” and it was way more funny.
