Quinn says Hey, did you hear Remy's father's speech the other day?.
The friend responds Yeah, he gave a pretty powerful message. What did you think of it?.
Quinn responds It was touching. At one point, I had tires in my eyes..
The friend responds Don't you mean tears?.
Quinn responds No, I mean tires.  You see, I used to work at a Discount Tire Factory, and his stories brought back memories from when I worked there.  I saw visions of rubber tires as he spoke..
The friend responds Your humour brings tears to my eyes!  But I could use another set of tires for my van....
