Today, we’re celebrating multiple birthdays (4) with multiple cakes (5). Besides yours truly, who had his birthday a few days ago, THREE other people will have their birthday next Sunday, so today seemed like a good day to treat all our colleagues. Below you see two of the cakes, a delicious (southern-) Dutch specialty called “vlaaien”, which you can get at Multi-Vlaai.

If you’re wondering why the cakes have funny faces, read this page on Saint Nicholas.
Puzzle: in a group of 60 people, how large is the probability of three people having the same birthday? For all you highly-educated people, this puzzle should be a piece of cake (sorry, couldn’t resist the pun).
