Continuity mistake: Russell first slept with Constance on his 18th birthday. He says she was 39 years old at the time. She is now 60, so 21 years have passed, making Russell himself 39 now. However, in the Season Two episode "Time Share", he admits to a magazine reporter that he is 42 years old. There is no indication that three more years have passed.
