An Irishman walks into a Chemist Shop with a small bottle of liquid and a spoon.
He says to the Pharmacist "Would you try this for me, and tell me what you think?"
He pours a little onto the spoon and the pharmacist tastes it...he makes a face as its quite unpleasant.
"Bleugh!" He says.
"You don't find it too sweet?" asks the Irishman
"No, its horrible"
"Thank goodness" says the Irishman "The Doctor told me to bring a sample of Urine in, to test it for excess Sugar!"
