Changing a flat tire

A guy’s on the side of the highway changing a flat.

A patrol car pulls up. The officer steps out and says, “Sir, we received a report of an emergency…”

Before he can finish, another cruiser comes flying up from behind, speeding in the same direction. It slams on the brakes and skids in behind the first car. The second officer jumps out, a little out of breath. He takes one look around and says, “Oh… I thought…”

Suddenly, from the opposite side of the highway, a third cruiser whips a U-turn across the median, sirens blaring, and screeches to a stop.

The third officer jumps out and runs up. “Are there any left?”

The first two silently point at the spare tire. The third officer squints at it.

“We really need better descriptions from dispatch, this is not what I would call a donut emergency”
