Madison, Wisconsin Puns

I'll be sitting in the passenger seat. Perhaps on my phone. My dad will point out to the street and say 'Hey'. Naturally this gets my attention. I usually respond with 'What?' He wont answer. I'll look over and he'll be pointing at a Truck transporting a large number of bales of hay. I look at him. Smuggest look of satisfaction on his face.
