His Trysting Places (1914)

On his way to a restaurant, Ambrose, a happily married man, obliges to mail a letter for a woman in the apartment lobby. Unbeknownst to him, the letter is about a rendezvous with her own lover at their "trysting place". Elsewhere, after some domestic frustration, Charlie runs an errand to buy a baby bottle before stopping at the same restaurant. After a confrontation there, they both inadvertently leave with each other's coats. Later, their wives independently discover what appears to be incriminating evidence of extramarital affairs from the pockets of the swapped garments. It all comes to a head when all four of them find themselves at the "trysting place" in the park.
