"That '70s Show" (8 p.m., Fox): They're calling it a decade on "That '70s Show." After 200 episodes and eight seasons, the sitcom that blissfully wallowed in the era of bell-bottom pants and 8-track tapes bids farewell. Ashston Kutcher returns to reprise his role as Kelso in the one-hour finale.
"Will & amp; Grace" (8 p.m., NBC): We aren't quite sure if "Will & amp; Grace" has earned "classic" status, but it certainly will be remembered for breaking prime-time ground and for some very funny episodes -- especially early in its run. After eight seasons, it all ends tonight with a series finale that immediately follows an hour-long retrospective special.
