The Yellow Cab Man (1950)

Hapless inventor Red Pirdy (Red Skelton) has difficulty keeping a day job due to his knack for being an accident magnet. Finding employment as a cab driver, Red quickly jeopardizes his new gig when he demonstrates his latest invention -- unbreakable glass. Upon seeing his technological breakthrough, a gang of criminals, including the shifty Dr. Byron Dokstedder (Walter Slezak), attempt to steal his invention, resulting in plenty of slapstick antics.
