Here's your hilarious joke:

Infinitely many mathematicians walk into a bar. The first orders one beer. The second orders half a beer. The third orders a quarter of a beer This pattern continues for a few more, and then the bartender stops them, and pours two beers. "Why'd you do that?" Asked the first guy. "Come on guys. I thought you knew your limits." Said the bartender.
