It's the sort of story that you'd expect to find showing up in numerous versions, but for some reason, even though I've told it countless times, I get the impression that people aren't familiar with it. For me, at least, it gives a wonderful description of the pre-internet version of virtual teaching.

A father returns home from work one evening and, as he customarily does, asks his son what he did that afternoon. "Today I taught the dog to talk", comes the response.
The father, torn between what he knows is possible and his trust in his son's capabilities, tries to clarify the situation a bit: "You did what?". And once again, the response: "Today I taught the dog to talk".
Not one to cast too many doubts on his son, the father gives in and accepts the situation: "Fine. What can he say?"
But the son responds: "He can't say anything".
"He can't say anything? But I thought you said you taught him to talk?"
"Oh, I taught him to talk, but he didn't learn."
