Cracking up

About a hapless misfit who seeks psychiatric help after bumbling a suicide attempt. His shrink sessions reveal a flashback history about a klutzy childhood and a family history of (what else?) ineptitude, affording Lewis to play a smorgasbord of roles, including a 6-year-old boy, a 15th-century coachman, a good-ol'-boy sheriff and a bearded guru. The wackiness soars to new heights when our nutcase patient takes a transcontinental flight on the cheapest airline he can find.
