You think maybe you can talk your way out of this. And here's what your panicked brain comes up with, five words guaranteed to do you no good:
I only had two beers.
The "two beers" line has been uttered so often that it's a joke among police officers. In 20 years of patrolling highways, Virginia State Police Trooper L.L. Parker has heard that slurred lie more times than she can remember.
"I don't know of any officer out here who, if you tell them you only had two beers, they'll tell you, "Okay, then, have a nice night,' " Parker said, chuckling. "But drunks, for whatever reason, they say it all the time."

"I guess they think two is the magic number," said Trooper Parker, chuckling again. "If you had three, you must have a drinking problem or something. . . . But if you only had two, then you must not be all that drunk."

"Two beers," said Elizabeth Wingo, a supervisor in the D.C. attorney general's office. "Everyone says that. Then they come in and blow a point-one-four."
