According to this short article in Atlas Obscura, one clock in Germany sticks its tongue out every hour and every half hour. I think I need this clock to make me laugh while I’m studying or working. Warning: the explanation of the clock is a bit morbid, and it may not make you laugh as hard after you know the origin. #blackhumor
The quality of this video is pretty awful (unsteady) but you can see the clock do its thing.
