Anonymous1: That's pretty much out of character, a smartass like Lisa needing an explanation what a penis can be used for. In the TV episodes she is 8, and even then she rolled her eyes when her brother was clueless about sex. Also, Bart's dick is rather small.
Anonymous3: Anon¹ - Lisa had a severe case of amnesia from bumping her head on hard asphalt after riding with Bart on his Harley Hog & he was forced to bring it down or get them both run over by a speeding truck that blew a redlight.
