Some people don't know when to quit or re-quit

Welcome back to the daily grind, Garth Brooks. Since you "unretired" from music on Thursday, you're probably stressed about how things are going to work out. • Rest easy, Garth. You'll be fine. After all, you may have friends in low places, but they're so in love with you they'd pack the Opry just to watch you play The Thunder Rolls on a ukulele. • When it comes to infamous retirements and changes of heart, you should wind up one of the lucky ones — or not …

Brett Favre

The Cheeseheads in Green Bay are ready to grill the Packers execs behind the forced retirement of their beloved QB. Especially this season, as Favre has donned a Minnesota Vikings helmet and led the hated NFC North rivals to a 5-0 start. If he raises the Lombardi Trophy at season's end, not even a bucket of cheese curds will pacify the GB faithful.

Verdict: Touchdown!

Indiana Jones

Fans thought Harrison Ford had hung up his fedora and bullwhip for good after 1989's The Last Crusade. But after the scathing reviews for 2008's Indiana Jones and the Kingdom of the Crystal Skull, the 67-year-old Ford should have snaked back into retirement. Sadly, writing has already begun on a fifth installment of the franchise.

Verdict: Blade Runner 2 — now that makes sense!

The Police

"Don't stand so close to me." That was more mantra than song title back in '86 when Sting, Stewart Copeland and Andy Summers retired the legendary trio among personal feuding and bitterness. But 21 years later, the trio had a "message in a bottle" for long-suffering fans: a sold-out reunion tour that was worth the wait. But don't hold "every breath you take" for more: Copeland released a tell-all, Strange Things Happen, earlier this month that made it clear that when it comes to working together, the boys were still the "kings of pain."

Verdict: "Every little thing they did was" — oh, forget it, you get the point.

George Lucas

When we last saw Luke, Leia and Han in '83, they were stuck on a forest moon with a bunch of annoying Ewoks. So naturally, sci-fi fans cheered lustily when Star Wars mastermind George Lucas returned in 1999 for a trilogy of "prequels." And the result? Jar Jar Binks? Really?

Verdict: Lucas should have stayed in an igloo on Hoth.

Seinfeld

Jerry, George, Elaine and Kramer called it quits in 1998 — not that there's anything wrong with that. It took series co-creator Larry David to bring the foursome back for a faux reunion on his HBO series Curb Your Enthusiasm. Entertainment Weekly says the chemistry is as tasty as "a bowl of mulligatawny soup." (That's good, right?)

Verdict: Grab a box of Junior Mints and just enjoy every second of the reunion.
