My uncle was a great fan of raising the younger generation, including by his example. There was little thought about credibility. One day at a family gathering he began to preach to a group of teenage nephews that it was too early for them to think about the opposite field, for example, he himself did not even think about any sex before graduating from the institute, because he understood what a responsibility it was!

The uncle son (at the time of the year 22-23), raised on the bikes from the series "How my mother and I wrote diplomas in the breaks between feeding and peeling" thoughtfully asked:

Dad, where did I come from then?

I think when my uncle heard this question for the first time in 18 years before that, he was less embarrassed.
