LOL: Watch Bill Murray As Peter Pan On 'The Late Show'

After 40 years in television, it takes a lot to confuse David Letterman. But that's exactly what happened last week when frequent guest Bill Murray flew onto his set as Peter Pan, singing and everything. Check out the video below.

Thanks to The Late Show for the video. Be sure to watch Letterman's totally awkward reactions.

Murray will next be seen in The Monuments Men, out February 7.
