I should have been a plumber

My plumber came over this morning to fix the sink and he's got a little apprentice boy with him today. He's just said to 'prentice boy "run quickly and get me a nipple... and an easy hooker". Now of course I'm thinking 'hell that's a little early in the morning for THAT ain't it?' but it's actually plumbing equipment. Wonder what else they've got in their bag of tricks....?
