One of Bart's early hallmarks were his prank calls to Moe's Tavern owner Moe Szyslak in which Bart calls Moe and asks for a gag name. Moe tries to find that person in the bar, but rapidly realizes it is a prank call and (despite not knowing who actually made the call) angrily threatens Bart. These calls were based on a series of prank calls known as the Tube Bar recordings. Moe was based partly on Tube Bar owner Louis "Red" Deutsch, whose often profane responses inspired Moe's violent side. The prank calls debuted in "Homer's Odyssey", (season one, 1990) the third episode to air, but were included in "Some Enchanted Evening", the first episode of the series that was produced. As the series progressed, it became more difficult for the writers to come up with a fake name and to write Moe's angry response, so the pranks were dropped as a regular joke during the fourth season but they have occasionally resurfaced on the show.
