Input: Question: There is a joke: Q: What is grey and comes in quarts? A: An elephant. Why? Why does it come in quarts? What is funny here? 
Answer: I feel like I'm walking into some kind of trolling here, but I believe the joke is based around the definition of "comes" which is synomymous with "ejaculates". In other words, the joke is implying that volume of the elephant's ejaculate is rather large: a "quart" of course being another word for a quarter of a gallon, aka two pints. The first-glance reading of "comes in quarts" would be "is available in quarts" (like milk), and the reversal of the understood meaning of "comes" is where the humour arises (if it does arise).
