Four Fold Puns

You awake in a room, it is dark, you are sitting in a fold up chair. You look down and feel your belly, it is rumbling. You look to the wall behind you and turn on the light. You turn back around only to see 3 dozen Dads telling jokes to each other and howling in laughter. You push through the crowd until you find your own father. Once you find him you tell him you're hungry. Immediately every dad in the crowd looks at you and simultaneously chants four words, "Hi Hungry, I'm Dad".
