Quote from Fez in Happy Jack
Eric: You know what? This is Donna's fault with her, you know, "No more sex till we're married" crap. You guys have no idea how hard it's been to have no sex at all. Fez: Yeah, it must be horrible. Eric: Seriously, you guys, what do I do now? Hyde: I say you've got to pull a Nixon. Deny, deny, deny. Fez: No, you just need a good story. Whenever I get caught, I just tell people that I'm checking for ticks. Hyde: Fez, how many times have you been caught? Fez: Oh, come on, I'm not stopping just because a doorknob turns.
