A dwarf is walking…

A dwarf is walking down the street and he picks up a hooker. He takes her back to his bedroom and she lays on the bed ready for him.He takes out a suitcase and unpacks four large springs, which he attaches to his hands and feet, climbs over her and starts to give it to her – bouncey bouncey!So anyway she is absolutely loving this and when he finishes she says ‘I’ve never seen that method before, it’s not in the Kama Sutra – what’s it called?’The dwarf says ‘Oh, that was the “Four-Sprung Dwarf Technique”‘
