What the hell am I supposed to do with a river of milk? I don't even drink milk like that unless it's with an oreo or a slice of cake, and neither of those two things are mentioned in Jannah.
You have this way of wording things that makes me laugh out loud.
"But brother you can have anything you want in jannah." If they didn't sell you on a shit-load of milk, this is what they tell you.
Some dumb muslim man (not a child mind you) was seriously telling other grown men that he's going to have all the pokemon in the world in jannah. He wasn't joking. Some muslims argued with him back and told him that cartoons were haram so he couldn't have it.
Theses jokers I tell ya.
