Common sport amongst contractors working away from home. Of an evening, should they be feeling frisky and risky, they may strip off, carefully climb up on to the B&B’s sink rim, tiptoes on the unsupported edge.

Martin: How was your evening Andy?
Andy: Pretty tragic really.
Martin: But I thought you had your night planned? Kebab and a crab-wank you said??
Andy: The kebab was great and I was after a thrill before bed.

Martin: Still, better than Steve last year, his sink shattered and cut his femoral artery.

Andy: Hummnn, I may go back to the floor for a bit…
