Jason Scott blogs about corporate artifacts, in one of his links is one of the funniest examples of such things. The IBM Song Book is just that a book of songs about IBM. Here is a snippet from one of the songs called 'Ever Onward'

Ever Onward! Ever Onward!
That's the spirit that has brought us fame.
We're big but bigger we will be,
We can't fall for all can see,
That to serve humanity has been our aim.
Our products now are known in every zone,
Our reputation sparkles like a gem.
We've fought our way through
And new fields we're sure to conquer, too,
For the Ever Onward I.B.M!
I can see the guys in blue suites singing this now, and it gives me the willies.
