"Another test" joke

There was a blonde driving a ferrari. A cop pulls her over for
speeding, the cop asks," can I see your license and registration
please!"
The blonde responds, "license and registration what is that?"
The cop respnds," you will find your license in your purse and
registration in your glove compartment."
The cop gets the license and registration and goes back to the car,
and he calls dispatcher and reports it. The dispatcher replies,"
this wouldnt be a blonde in a ferrari would it?" The cop replies,"
yes it is." The dispatcher says, "go back to her car and drop your
pants."
The cop responds back,"I cant do that!" The dispatcher says, "trust
me, just do it!" then the cop replies,"ok whatever you say!"
So he walks back to her car, and drops his pants. The blonde turns
around and says, "oh no, not another breathalizer test!"
