A Londoner, pinched for drunken driving, was submitted to a new testing machine which registered a staggering percentage of alcohol in his breath.

"Your machine must be on the blink," insisted the Londoner.

"My wife's a teetotaler. Try it on her."

The police obliged and again the machine showed alcoholic content far above the allowable level.

"Now I KNOW your machine's out of order," cried the driver. "To prove it, let our little baby blow into the thing." The baby's breath was sampled, and sure enough, proved high on the alcoholic side.

Sheepishly, the police tore up the complaint.

Driving triumphantly away, the Londoner told his wife, "That was one wonderful idea of yours to give the baby those two slugs of gin before we left the pub."
