Fellow-You seem surprised.
Girl- Oh, most of the guys that come in here have them. 19 out of 20, I'd say.
Fellow, puffing out his chest- Well, then, thank you much. Is that what I smelled walked in here?
Girl-No, that's just my upper lip, from the Dirty Sanchez I had for breakfast.
Fellow- I thought you said I was your first!
Girl-Oh, yeah, you're right. I guess I must have just shit myself.
Fellow, relieved- Oh, Thank God!
