Damned handy to find a barrel with those words painted on. Usually when a man experiences Sudden Poverty Cliches he’s stuck with whatever he can find.
The circumstances of barrel-wearing were never explained; we’re just supposed to assume that the person has no other options, and has been forced to sell all his garments save his suspenders. Presumably a barrel was procured before that transaction.
Standing on a cloud in an Islamic country with a fellow who’s wearing matching underwear and stole a towel from a hotel is just par for the course, but when the other guy uses a wind instrument to charm up a girlsnake, that’s when he drops the binoculars.
