From the Salt Lake Tribune:
Attorney fined for zapping witness with trick pen at dairy cow trial
In an order released this week, 4th District Judge James Brady wrote that electricity expert Athanasios Meliopoulos was testifying against dairy farmers who claim that "stray" currents from Intermountain Power Plant in Delta were harming cattle.
As part of his testimony, Meliopoulos claimed that 1.5 volts, the equivalent of a AAA battery, could not be felt by a person. Los Angeles-based attorney Don Howarth, who represented the dairy farmers, gave a child’s gag pen to Meliopoulos. According to the package label, the retractable pen zaps the user with "a harmless powerful shock," Brady wrote.
Howarth told Meliopoulos that the pen contained a 1.5-volt AAA battery and challenged Meliopoulos to "go ahead and push the back of the pen and tell the jury whether you feel it or not," Brady wrote.
Meliopoulos, a Georgia Tech professor, pushed the pen and "received a strong electric shock, which caused his body to jerk and to drop the pen," Brady wrote.
