Liberace might be more popular now than he ever was back in the day!
Now Bill Murray wants to get in on playing dress up as the piano tickler!
On last night's Late Show 20th anniversary special, the funny man made his entrance in a white Rolls-Royce and dressed from head to toe as Liberace!
Billy camped it up as he kissed David Letterman on the cheek. He then told the crowd:
"I love you audience, I love you. But I don't have time tonight. Because I'm only here for one reason!"
Murray then lovingly pointed in Dave's direction!
After two decades of appearances, Bill decided now would be a good time to dig up the time capsule he buried underneath's Dave stage!
Using a pickax and a jackhammer, Billiberace got his hands dirty but managed to find the lock box he hid in 1993 that included Letterman's old toupee!
You HAVE to ch-ch-check out the rest of Murray's very special visit, including the song he sang to celebrate Dave's big occasion! (below)
