Monkey Man the speeder...

State police in Arizona aren't chuckling at a driver who triggered Phoenix-area freeway speed cameras more than 80 times in a year while wearing monkey or giraffe masks.

The Arizona Department of Public Safety says the driver is 47-year-old flight attendant named Dave VonTesmar.

But VonTesmar says authorities can't prove he's the one behind the wheel of his car, and he's vowing to fight every ticket.

By the time police realized the masked man's ploy, more than 50 tickets had been voided because the deadline for prosecution had passed. VonTesmar was served with a summons on 37 tickets last month.

Nearly 500,000 tickets have been issued from the first-in-the-nation statewide photo-enforcement program since it went into effect last September. But only about 132,000 recipients have paid the $181 fines.
