Two Scotsmen had been pals since childhood and had shared everything over the years.

One day, Angus won a rare bottle of Scotch in a door prize.

Immediately, Jock says "Open it up and we'll have a dram."

"Naw, ah'm goin' tae save it for a special occasion."

Birthdays came and went, his anniversaries came and went, but Jock could never get Angus to open the bottle.

Finally Angus had a heart attack, and was laying on his deathbed.
He motioned for his old friend to come closer.
"Jock, remember that rare bottle of Scotch I won?"

"Aye, ah certainly do, Angus!"

"Weell, ah like ye tae do me a favor Jock, my dear friend."

"Aye, anything ye ask Angus."

"When ah'm dead, wid ye take that bottle an' open it up--"

"Aye, Angus, then what?"

"Wid ye pour it over ma grave?"

"Pour it over yer grave? My god Angus. It's 40 year old Scotch! But I'll do it for ye."

"Oh, ye're a real pal Jock, and ah'll appreciate that."

Jock says,
"There's just one thing Angus, wid ye mind if ah filter it through my kidneys first?"
