Rising Damp S04E04 - Pink Carnations

By coincidence Rigsby and Ruth answer the personal ad each has placed in the local paper and meet at the same hotel, both wearing pink carnations for identification purposes. Then a bridal party arrives for a reception and, as both bride and groom are also sporting a pink carnation, this leads to confusion as both get mistaken for the blind date. When the bride's mother comes to sort things out Rigsby is horrified to think that she might be the person he has arranged to meet and insults her before getting thrown out, still unaware that Ruth was his real blind date.
