Keeping it clean

It can be really, really difficult talking to my friend Darryl:

Darryl: Washing your hands is bogus.
Harvey: I couldn't disagree more.
Darryl: It's a waste of time and a waste of water. Do you hate the earth?
Harvey: You're objecting to hand-washing on environmental grounds? Just yesterday you said "recycling" is bogus.
Darryl: Recycling is totally bogus.
Harvey: Look, not washing your hands is disgusting.
Darryl: My hands seem OK, and I haven't washed them all day.
Harvey: They're not OK! Your hands are filthy. What the hell did you do to them?
Darryl: It's chocolate. I mean, I think it is.
Harvey: You don't know?
Darryl:
Harvey:
Darryl: Maybe I should wash my hands.
Harvey: I gotta go.
