another joke !

This joke is funny to me because it appeals to my "medical" background, but others may find it "uncouth"
Nevertheless, it's still funny !

Two old people, a man and a woman, walk into a hospital.
The doctor says to the old man, "I'll need a urine sample, a faeces sample, and a blood sample."
The old man says, "Eh, what ?"
So the doctor says it again.
Once again the old man says, "What ?"
So the doctor yells it, "I NEED A URINE SAMPLE, A FAECES SAMPLE, AND A BLOOD SAMPLE!"
With that the old woman turns to the old man and says, "He needs a pair of your underpants !"

Hi Krystyna
I told your joke to Patrick and he found it very funny.

Hi Muriel,
If Patrick found it funny, then he would be very comfortable working in a hospital or medical centre in Australia !
The doctors and we nurses spend a lot of time laughing at such jokes !

Indeed, very funny! Thanks Krystyna!

I want to work in an Australian hospital as well!!... for the jokes only!
