All these posts but not this old PC joke. In Alberta I first heard it while taking coffee in a Hutterite Colony, largely surrounded by farms owned by descendants of Ukrainian immigrants.

How many Ukrainians does it take to change a lightbulb?
Fifty-one. One to hold the bulb and fifty to turn the house around. The joke was told about Hutterites in the Ukrainian households.

This worked as a Blonde joke or hillbilly joke or mechanic joke or civil servant joke or- pick your category. But I'm sure everyone has heard it by now.
