Spank, one of Louisa Cappellini's pet monkeys, plays bass guitar in the Late Night Buffet with Augie and Del house band, Louisa Cappellini and her Four Course Band.
The puppet created for Spank was later used as Yeager in the Henson series The Simian Undercover Detective Squad and in No, You Shut Up! as Professor Cornelius Nougat.
The same puppet later appeared in the Neil's Puppet Dreams episode "The Restaurant" as a monkey patron (performed by Allan Trautman).
Spank's puppet later appeared in No, You Shut Up! as "chimpthropologist" Professor Cornelius Nougat (performed by Ted Michaels).
