A similar story happened to two friends of mine when we were in yeshiva in Israel.
Both were Dovid and both had dates on the same night through the same shadchan.
I’ll never understand why, but the shadchan set up both dates to meet at the same place in the same hotel. A few minutes in one Dovid realized he was dating the wrong person and went to find the other Dovid (and his date) so they could switch.
Another similar story- one shadchan thought she had a great idea for a guy I knew from yeshiva and wanted to speak it over with another shadchan before she suggested it. The second shadchan thought she was talking about another guy and decided to call him and suggest it before the first one did (since it was such a good idea). The second guy ended up getting engaged to her.
