3rd Rock from the Sun - Season 6 Episode 13

Nina accuses Dick of knowing nothing about Mary, so in an attempt to prove her wrong, when Judith walks into the office announcing that she has two tenth-row tickets to a Gordon Lightfoot concert, Dick claims to already have front row tickets. Of course, he doesn't, and so attempts to find a pair of front row tickets before it is too late. Meanwhile, Sally tells Chaz, the Channel 10 anchorman, that she would like to start presenting the news instead, and so he agrees to let her interview Lightfoot in the company's box at the Rutherdome; but really, he intends to seduce her.
