Irish Joke

One day an Irishman goes into a pharmacy, reaches into his pocket and takes
out a small bottle and a teaspoon. He pours some liquid onto the teaspoon
and offers it to the chemist.

"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."
