We are all familiar with the usual suspects but who are the obscure comics you would either see in person or watch over and over again on YouTube?

I have seen Jim Gaffigan twice in person - once in Mansfield and once in Seattle and his show is a can't miss IMO. I have also seen Brian Regan and he was side splitting. 

Here is my first entry to a stand up bit that I re-watch over and over again. 

Who are yours?
