Quote from Adrian Monk in Mr. Monk and the Bad Girlfriend
Natalie: Okay, then let's do it. [hands Monk a helmet] Adrian Monk: Yeah, I don't think so. Natalie: Brand-new, straight from the factory, nobody's even worn it. Adrian Monk: Eh... Natalie: Mr. Monk, if you don't put it on, bugs are going to fly into your mouth. Adrian Monk: Can't you just avoid them? Natalie: I can't avoid the bugs. Adrian Monk: Sure you can. You see a bug, zigzag. See another bug, zigzag. Natalie: If you don't put it on, we're not going.
