Summer hit Puns

I wash windows for a summer job when i am home from college.

Today I was washing a window to a nail salon when an older gentleman was walking past, and he hit me with a zinger.

"How's the window washing business going?"

<without waiting for a response> "You must be cleaning up!" He then walked away chuckling to himself.

So this was in the summer of 2011 and at the time this song was a big hit: Medina - You and I. The important part here is the chorus, starting at 0:44.

So in the middle of the song I ask my friend "Do you know what kind of car this singer drives?"
"No idea", she said. To which I replied "A hyu-n-dai."

She almost threw me out of the car.
