When Jerry is talking to Elaine about thinking of breaking up with his girlfriend, Elaine is eating a cookie saying is the 4 o´clock dosis or whatever. Then Jerry says he will call his girlfriend to break up and Elaine tells him that those days are over and that he should go over to her place and break up with her in person. He says he´s afraid of the killer and Elaine says is still daylight.
When Jerry finishes breaking up with his girlfriend he asks "what time is it?" and she says "9". He then asks "We´ve been breaking up for 10 hours?". If so, he would´ve had to be there since 11 am, but it was around 4 pm when Elaine told him to go, so it´s inaccurate.
