PY – let’s fix that joke. First of all, we start these things at night. Second of all, we start Mashiv HaRuach on Yom Tov so it wouldn’t be just 4 seconds difference. Third of all, why didn’t his wife remember from last year?
The joke is about the a newly wed Yekke who comes home 4 seconds late one December night. The punchline is we started to say V’sain Tal U’mattar tonight. Everything else is excatly how you said it.
But as usual, Nobody cares.
