Many dilemmas in life can be answered by asking oneself one simple question: "What would Bill Murray do?"
And if you were Bill Murray and you'd been invited to throw the first pitch of the season at Wrigley Field, the home of the Chicago Cubs baseball team, what would you do?
Would you just walk on to the pitch and throw the ball? Of course you wouldn't. You'd run around all the bases first.
Just click on the video above to enjoy the downright silly (and thus quintessentially Murrayesque) moment - and on the videos below to enjoy clips from 10 of our favourite Bill Murray movies.
"This is one time where television really fails to capture the true excitement of a large squirrel predicting the weather." From meeting Ned Ryerson to being slapped by Andie MacDowell, enjoy the best bits of weatherman Phil Connor's day-on-repeat.
Witty Ghostbuster Peter Venkman is possibly Murray's greatest on-screen creation - and while there are a wealth of classic Venkman moments to choose from, we just had to go for "Cats and dogs living together..."
'Bill Murray is back among the ghosts - only this time, it's three against one.' So ran the tagline for this '80s reworking of Charles Dickens' <em>A Christmas Carol</em>, now a seasonal favourite for just about everyone between the ages of 25 and 45.
We'd like to tell you what we think of <em>Lost In Translation</em> - but that would involve us whispering in your ear and everyone else wondering what we said. So instead, we give you... "Suntory time!"
Quite possibly the finest film about golf - though we realise there are very few contenders - <em>Caddyshack</em> was Harold '<em>Ghostbusters</em>/<em>Groundhog Day</em>' Ramis's first feature film. In it, Bill Murray plays greenskeeper Carl Spackler - who spends most of the movie trying to kill a gopher.
Hugely overlooked, the 1990 comedy <em>Quick Change</em> marked Murray's first - and so far only - foray into directing. And as this opening sequence shows: you can dress Bill Murry up as a clown - but he's still unmistakably, wonderfully, always Bill Murray.
Like the rest of the cast of this comedy classic, Bill Murray is note perfect as Dustin Hoffman's flatmate/confidante/pretentious fellow actor, Jeff. Check out this scene in which Jeff holds forth at a party - <a href="http://youtu.be/smTXkhM6v-Y" target="_hplink">and this one for his unforgettable "nutty hospital" one-liner</a>.
<em>Rushmore</em> didn't just bring Wes Anderson to everyone's attention - it also marked Bill Murray's move into 'serious' acting (albeit with a comedic twist. Always.) Here's one of our favourite moments, in which he takes to a diving board... with a cigarette and drink in hand. Of course.
A scene from the musical-turned-movie which doesn't just feature Bill Murray as a masochistic patient - but also Steve Martin as a sadistic dentist! Boom!
It's Bill Murray! Bowling in a wig! In a Farrelly brothers movie! Sorry - was I talking out loud?
