Yksi, kaksi, kolme is one, two, three. What comes next depends on which Finland you have been introduced to. In this case it is the sauna, which is the correct answer and the one most Finns would arrive at without needing the count.
The sequence on this shirt is not a joke about Finnish culture so much as a summary of Finnish priorities. The numbers are the formality. The sauna is the point. Everything that comes before it is just counting toward where you were going anyway.
Wear this on the way to the sauna, or on the way back, or at any point in between when someone needs a reminder of the order of operations.
