(after hearing Kelso's song about Jackie)
Eric: Well...I think that you should draw her a picture.
Kelso: Hey pal, you think you're funny? Well someday Donna's gonna crush your stupid little heart, too!
Eric: Yeah...see, I don't think so because I've taken special precautions to prevent that very thing from happening. For instance, I don't sleep with other women.
Kelso: Yeah, well it's only because you're chicken!
