A veteran Metro mechanic has been fired, and three top executives suspended, after the mechanic told a dirty joke to a crowd at a departmental awards ceremony, The Examiner has learned.

Gene Garritt volunteered to emcee a banquet in Prince George’s County for elevator and escalator apprentices Sept. 17. Taking the microphone, he told dirty jokes. The humor was lost on someone in his audience, who reported Garritt to Metro authorities.
