I first heard it in 1989, when an older kid told me it. He then had to explain the punchline, because I was seven. To this day, I've still not laughed at it.
Here's another from that era I was reminded of today......
So this guy buys a breeding pair of budgies, but day after he takes them home finds the female dead, ripped to pieces, on the bottom of the cage, with the male posing in front of his mirror.
He tries to introduce two more females on the following days, but the same fate befalls them.
Annoyed with this he decides to punish the budgy and puts a male crow in the cage with it, to teach it a lesson.
Following day he finds the crow dead too, so he puts a kestrel in thinking that would an end to it.
No such luck. The kestrel was brown bread the following morning, too.
'Right, I'll have the little bastard' , thinks the guy, and gets hold of a golden eagle and sticks that in with him.
Next day he checks the cage and the budgy is completely bald, feathers on the floor, next to the eagle.........dead.
The guy says 'Jebus, that looks like it was a bit more of a challenge'.
The budgy looks at him an says 'Yes, I had to take my coat off for that fecker.'
Apologies, it's better when yer drunk.
