A young girl started work in the local chemist shop and was naturally very shy about having to sell condoms to the general public.

The owner was due to go on holiday for a couple of days and asked if she would be willing to run the shop on her own, so she had to confide her worries about selling contraceptives.

"Look," he said, "My regular customers donít ever ask for condoms; usually they just ask for a 310 [small], a 320[medium], or a 330[large]. The word condom is never actually used..."

The first day was fine, but on the second day this black guy came into the shop, put out his hand and said, "Er, 350 please!"

The girl immediately panicked, ran out of the shop and phoned the owner on his mobile to tell him of her predicament.

"Go back in and check to see if he's got a yellow bucket hanging between his legs," the boss calmly told her.

She peeped through the door and saw the yellow bucket hanging between his legs. "Yes!" she said, "He's got one hanging there!"

"Right," said the boss, "Now go back in and give him £3.50...

"He's the window cleaner!"
