Firefighters! You gotta love 'em. They save lives. They put out fires. They make a nice pot of chili. And sometimes they screw sheep, too! At least that's what Mesa deputy fire chief Leroy Donald Johnson was accused of doing last March, when he was busted for allegedly screwing his neighbor's lamb. What made this particular chorus of "Baa Baa Fire Chief" so fun to sing was the accompanying police report, an eight-pager (with pictures!) so full of yuks you'd swear it was a hoax. According to the report, when Alan Goats (we swear, that's his name) found Leroy in his barn ? his pants around his ankles and a small gray ewe between his legs ? Johnson laughed and hollered, "You caught me, Alan, I tried to fuck your sheep!" So there's little question that, er, mutton happened. Rather than leaving Leroy on the lamb, coppers hauled him off to the Fourth Avenue jail; later, Mr. Johnson (who was charged with disorderly conduct and criminal trespassing) was dumped by Mesa firefighters. But he'll always have his Lambkins.
