Bill Murray turns 65 Monday, and we think that's really something to celebrate!
After all, the actor-comedian has been making us laugh ever since he first hit the "Saturday Night Live" stage as one of the Not Ready For Prime Time Players in 1977.
Since then, he's made his mark in a variety of comedies and dramas on the big screen, including unforgettable roles in "Caddyshack," "Ghostbusters," "Lost in Translation" and so many more.
But some of Murray's most entertaining moments never appeared on the big or small screens.
In honor of his special day, we've got an assortment of those unrehearsed gems:
1. Bachelor Bill
In May of 2014, Murray crashed a bachelor party at a steakhouse in Charleston, South Carolina. Sort of. The groom and company had actually requested the actor's presence, but he declined — before barging in later to share some sage wisdom.
(Warning: There's a bit of NSFW — but totally safe for a bachelor party — language.)
"You know how they say funerals are for the dead, not for the living?" he began. "Bachelor parties are not for the groom; they're for the uncommitted."
2. Birthday Bill
If various YouTube clips have taught us anything, it's that Murray is the man you want at your party — no matter what kind of party it is.
In September of last year, the funnyman took the floor for a friend's birthday bash, dancing, playing air guitar and just being the all-around life of the party.
3. Baseball Bill
The star is part owner of minor league baseball team Charleston RiverDogs. He's also the team's official Director of Fun, and it's clearly a job he takes seriously.
When fans in the stands had to sit out a rain delay in 2012, Murray hit the tarp-covered field and had the crowd howling with his slip-and-slide routine.
4. Baseball Bill: The second inning
Murray is the go-to guy for first-pitch fun, too. He's had a few entertaining efforts at the mound, but none beat his 2012 showing at Wrigley Field.
Rather than simply throwing the ball, he threw off his glove off for a rogue — and remarkably fast — run around the bases, complete with a mini-slide.
5. Pebble Beach Bill
He knows his way around the links, too, and he knows how to infuse his own brand of humor on the course.
During a 2010 effort at Pebble Beach, he kept the usually quiet crowd in stitches with his near-constant antics.
6. Photobombing Bill
When Erik Rogers and Ashley Donald posed for professional engagement photos, they never imagined they'd be joined by a famous face — but Bill Murray showed up for some impromptu fun all the same.
Making his way into a photo when it's least expected is long established habit of his. Here's hoping he keeps it up. We can't wait to see where he pops up next.
Happy birthday, Bill!
