Quote from Kelso in Young Man Blues
Hyde: Hey, did you show up in a cop car? Kelso: Yeah. My training officer let me take the cruiser out for a spin. Hyde: Mind if we check it out? Kelso: Fine. Just don't touch anything. I'll be in the bathroom taking care of some police business. Or as the boys down at the station like to say, I'll be taking a 10-100.
