So, a milkman......

.....was delivering milk in the neighborhood as usual.

When a blonde answered the door, she told the milkman to follow her to the bath-tub.

Then she took of her clothes and asked the milk-man to fill the tub with milk.

The milk-man said: "Do you want the milk pasteurized?"

And the blonde replied: "No, just up to my boobs. I can splash it in my eyes."
