Last week, he was in Florida, singing “House of the Rising Sun” for restaurant-goers and wearing PBR-printed pants. On Wednesday night, Bill Murray struck again, staging a takeover of “Late Show With David Letterman” in order to cross off a few items on his life’s to-do list.

As Murray told the host (and his long-time friend), he isn’t dying, but he’s still quite concerned with accomplishing all the goals he’s set out for himself. Most people would take movie stardom and cult hero status — not to mention an open invitation to appear at literally any party in the world — and be satisfied, but not Murray.

Among the things he had to cross off his list on Wednesday: Telling a joke in place of Letterman and meeting Lady Gaga (and subsequently taking a selfie with her, because all celebrities take selfies in public now).

Given his predilection for showing up anywhere at any time, one can only imagine what else Murray has on his bucket list, but hopefully more of it gets broadcast on television.
