He'd been rolling in his grave for at least a decade already before he died.

That's what really got me about this, and why it took me two viewings to get through it. The impression really isn't too terrible, but replacing "Shit" with "Data" only works in four or five of his examples, yet he takes it through the entire bit.

If this was Ted from accounting getting up and doing a skit for his coworkers, not so bad. But if this guy actually makes a living impersonating Carlin, holy shit.

It also strikes home on exactly how Carlin was not funny that fraction of the time when he was not funny. I love Carlin, but flawlessness wasn't necessarily his strong suit. He was more of an originator.
Anyway, this is excruciating- stars.
