Mr. Bean Goes to a Première (1991)

Mr Bean waits in line after a royal premiere at the Odeon Leicester Square to meet the royal visitor. Unfortunately, he finds that his breath smells, his nails and teeth are dirty and his shoes are grubby. He manages to rectify these by using his customary inventiveness (spit to polish his shoes, a loose thread hanging from a nearby waitress' uniform to floss his teeth) just in time to meet the royal. Preparing to bow, he accidentally headbutts her. She falls to the ground and Bean makes a run for it in the melee.
