Weird algebra message coming up - is this a joke??

Some users on our forum are reporting this message coming up from time to time:

Congregations, if your a member of this forum then you have successfully proved that your smart enough to be in Mr. Markis' Algebra II class.
2(-6 + x) = -2x
-12 + 2x = -2x
-12 = -4x
x = 3
You've made it into Markis' Algebra II course with a 99.95% A. You have been accepted into your unversity college.

We don't have karma enabled and the mods we have installed (that are working) are membergroup color links and biographies. We did have some other mods but none of them are working as they're not compatible with the upgrade so I don't know if that would affect things?

So my question is where does that message come from and how do we get rid of it?

Many thanks!

Could you copy and paste a list of the mods you have installed.

Also, where does the message appear?  How often is it displayed?
