Boing Boing had a post titled "The Nerdy Dozens", where on Xeni Jardin's twitter account a bunch of very nerdy "yo momma" jokes appeared. A lot of these were hilarious, so to preserve the ingenuity I collected the most nerdiest ones. Kudos to those who came up with these! Starting with my favorites:

• Yo mamma so fat, China uses her to block the internet.
• Yo mama so fat pkzip can't compress her.
• Yo momma so fat, it takes 5 warlocks to summon her.
• Yo momma so fat you gotta address her in 128 bit.
• Yo momma so fat they mapped her for Google street view.
• Yo momma so old she goes on carbon dates.
• Yo momma so stupid, she's currently on a quest for the Head of Vecna.
• Your momma is so mean she stole the walrus' bukkit and ate kitteh's cheezburger.
• Yo momma so mean she has no standard deviation.

A collection of "yo mama / your momma / your mom / your mama" (or whatever you want to call them) jokes - math style:

Your Momma is so dumb that she can't even solve a second-order non-homogeneous differential equation!

Your Momma is like a protractor.....good at every angle.

Your Momma prefers 77 to 69 because she gets 8 more

Your Momma is so stupid she thought that e^(pi*i) was equal to -2.
