Decent enough theme of "No way!" defined in four different ways. FUHGEDDABOUDIT (17A: "No way!"), while somewhat funny, is the weakest, as its spelling is not rigidly defined. I mean, other variants must exist for this one, right? Or would you say "THATSRIDICULOUS" to that claim?
Lots of usual early-week fare, and some words that exist more in crosswords than in real life. To wit: VEND (3D: Sell), LULUS (19D: Doozies), ISLE (55D: Archipelago component), and RIA (57D: Narrow coastal inlet). There are also appear several names that in these grids are weekly kept alive, like GAYE (35D: Marvin of Motown), BOHR (13D: Physics Nobelist Niels), and THOR (50D: Norse god of war). QUEST (5A: Knight's pursuit) and QUAKED (5D: Trembled, as with fear) provide some excitement in the North, but HIPTO (28D: Savvy about) belies a certain "unhipness" in both clue and answer. See also PONG (39D: Video game with a paddle). Is that trying to trick Wii players, or is it just old-fashioned? Hard to tell.
Not terrible. Not great. Monday.
