A Barber at Cutting Edge

The subject says:

Number five on top and two on the sides. Don’t worry about a rinse.

The Barber, Barry, replies:

So, going anywhere nice this Easter?

The subject:

No, probably not. I’ve just got back from Chad where I tamed a wild Elephant and fed it Jaffa Cakes.

Barber:

That should be nice. So, what do you do for a living?

Subject:

I work with the skull. Around twenty to thirty a day. Usually more if a bank holiday or Christmas is coming up.

Barber:

My old man’s mate used to be some kinda doctor too. Messy business, but then I’m screamish. What’s the worst you’ve seen?

Subject:

One guy’s nut had lice in it. Hadn’t been washed in years. Hairy knots and tangles all the way through.

Barber:

Well, blow me down. Who’d have thought a brain would grow hair?

Subject:

Yeah, people and their brains… who’d have thought it?

Barber:

So then, tell me how I should wash mine.
