An apt tribute.  Typically, comedians' only goal is making the audience laugh.  This guy very often delivered a style of comedy that seems almost deliberately meant to elicit confusion rather than raw laughter.  Doesn't at all mean the jokes aren't funny, IMO in his case, many jokes were so well engineered, the audience would need time to process them before visceral laughter emerged, and if everyone else is silently confused too, let's be honest, it makes it harder to laugh.  But again, doesn't imply the jokes aren't good!
