He crashed this guy's bachelor party and gave him priceless advice...
...when he popped into this couple's engagement photo...
...when he showed up for the "Bill Murray Ice Cream Social"...
...when he dressed like the bard on the Late Show With David Letterman...
...and like Peter Pan...
...and Liberace for the Late Show's 20th anniversary...
..and a jockey...
...and in football pads to mark David Letterman's 30th year on TV, which happened to fall right before the Super Bowl...
...and as if he was hanging out in his own basement...
...and then spruced up to take this selfie with Dave and Lady Gaga...
...and wore this playing golf...
...and tried his best to blend in...
...and teed off in this hat...
...and wore this tie and epic pair of pants at one of his charity tournaments...
...and these PBR pants at another...
...and when he whipped out this tiny camera at the Moonrise Kingdom photo call at the Cannes Film Festival (you know, while wearing this jacket)...
...and drove this vintage Maserati with bright-orange interior through midtown Manhattan...
...and went off-script at the Oscars to pay tribute to Harold Ramis...
...and when he resisted the idea of Ghostbusters III...
...and wore this at a Monuments Men screening...
...and when this happened...
...or when he joined these folks for basketball...
...and last but not least...here, when he raised $10,000 lying down.
