Ship's Least Favorite Food

Alright, listen up, genius. See, the joke is that a ship's least favorite food is "iceburgers." Get it? Like, icebergs, which ships, like, crash into? And the word sounds like "iceburgers," which is like, a burger made of ice. You probably think ice is only good in your sippy cup, but it can sink a ship! Get it now, smarty pants?
