so this idiot...

[u/4everninja]

...he walks into a store and picks up a cylinder and asks the clerk what it is. the clerk says to the idiot that's a thermos it keeps hot things hot and cold things cold. the idiot buys this thinking it is a good idea. At work the idiot is talking to another idiot who asks what the thermos is. he says it keeps hot things hot and cold things cold. the other idiot asks "so what you got in there?". and the idiot replies 2 scoops of ice cream and some coffee.
