I for one can't wait. After being a strong Leno fan prior to his taking over the reigns from Johnny Carson, I have come to pretty much loathe his crude humor. "Crude," you ask? The Oxford American Dictionary tells us that one of the meanings of the word is of course:
(of language, behavior, or a person) offensively coarse or rude, esp. in relation to sexual matters: a crude joke. See note at rude.
But when I call Leno "crude" this is the meaning I intend:
constructed in a rudimentary or makeshift way : a relatively crude nuclear weapon.
• (of an action) showing little finesse or subtlety and as a result unlikely to succeed : the measure was condemned by economists as crude and ill-conceived.
Conan is ingenious. Leno is crude.
