You can "try" to argue the radar gun if you want, or just try this.

"Do you know how fast you were going"? That question, yuck.  But in this case, at least the officer got a laugh out of it.

In Oakland, California a man was pulled over for going fast...99 mph in a 65, fast. When approached by the officer, the man had an odd statement: “I wasn’t driving that fast, the display must be the current temperature.” For the record, it was 80 degrees, nice try.
