Butch Cassidy relaxes after a robbery, giving the Sundance Kid an idea: what if on their next bank heist they use the drive-thru window? It would make for a fast sure getaway, horses getting notoriously dead when punctured by the bullets of pursuing lawmen. The bike besotted Butch decides it's the future and agrees.
The day of the heist starts with a bad omen when the Sundance Kid gets SMIDSY
'd by a stagecoach, totaling his black beauty. They make lemonade out of lemons and rob the coach out of principle, then the Kid hops onto Butch's handlebars. On the way to the bank they get passed by an old lady on a penny farthing, which irritates the Kid enough to want to rob her too, but Butch tells him to grow up.
When they finally arrive the drive-thru has a long line of customers who make easy pickings for the bandits. Flush with cash by the time they get to the window, Butch nearly has a change of heart and makes a deposit instead, part of him thinking he's getting a little old for this and maybe it's time to let his money do the work, but the interest rate is risible so he sticks to the plan. They take out a large withdrawal and commence their getaway.
Unfortunately the plan has a fatal flaw. The posse following in hot pursuit reminds them that bikes can get punctures, too.
The desperadoes take cover in an abandoned shed at the edge of town, pinned in, outgunned, their useless "hearse" as the Sundance Kid is now calling it a convenient target for him to flog out of frustration. Butch watches impassively, the posse giving the usual spiel about being surrounded, etc. "They also shoot iron horses, don't they," he says mostly to himself. "What?" says the Kid. "Never mind," says Butch. "For a moment there I thought we were in trouble."
