You'll never know when or where Bill Murray will show up.

He was there last night in Austin, Texas for Lupe Fiasco's show at the Belmont.

Not only did the funnyman stay to the end, but he forced his fellow Chicagoan to do an encore.

Murray never was able to rescue that Wu-Tang album from the clutches of pharmadouche Martin Shkreli.

But he was able to get some fans in Austin more Lupe.
