I'm no Brown Sharpie rival...

Brown Sharpie is a comic site written by a math graduate student. I'm not smart enough to understand everything, but I can pretend to laugh at almost anything. (You can search by title, this one is under culture.)


Hilbert's paradox of the hotel (wiki it here) is a hotel with infinite rooms that are all full. Luckily for this comic, both the rooms and the bus sets are countably infinite, so there really should be enough rooms. But what a dilemma for the concierge! My favorite part of this is in the speech bubble. Go ahead, laugh (or just sparkle your eyes in amusement.)

Now, there is no reason to ask, "What has Julie been doing with her time since swimming is over?"
