I know of him, but I, being the quite young adult that I am, don’t know too much about him except the few times I saw him on TV, and when I heard he had died quite recently.
But, hey, at least knowing of counts, right?
But was he who?
Aimi, knowing him definitely counts! I was so surprised of my two shami friends, both slightly older than I, who had never heard of him before. (That shock is what started this thread :-P)
Sakura, he was a comedian known for insulting the crowd (but in a good way). 
What’s the crowd?
The audience.
