Michael McKean tells Stephen Colbert how he sold the script for “Spinal Tap”

Last night, the eternally delightful Michael McKean stopped by The Late Show to share some memories from his decades-long career in comedy. He was there promoting the upcoming season of Better Call Saul — in which he plays Bob Odenkirk’s brilliant and troubled brother – but he spent most of his time telling Stephen Colbert about Spinal Tap, his first Late Show appearance, and his surprising super power (spoiler alert: it’s arthritis).

Season three of Better Call Saul premieres April 10th on AMC.
