One day an Irishman goes into the neighborhood pharmacy - reaches into his pocket and takes out an Irish whiskey bottle and a teaspoon.
He pours out a teaspoonful and offers it to the pharmacist.
"Could you taste this for me, please?"
The chemist takes the teaspoon, puts it in his mouth, swills the liquid around and swallows it.
"Does that taste sweet to you?" says Paddy.
"No, not at all," says the chemist.
"Oh that's a relief," says Paddy. "The doctor told me to come here and get my urine tested for sugar."
