The Likely Lads (1964)

Terry Collier and Bob Ferris are good friends. Terry was working class and secure in his life, whereas Bob was more aspirational, determined to work his way to a better place. Both viewed the others' worldview with disdain, but they were united by events, generally revolving around the pursuit of women. Although 20 total episodes were filmed, only 10 are currently known to survive. There is one missing from the first season, three from the second, and six from the final run.
