Quote of the Day - Reality Edition

Unix-Jedi put the last part of this into a comment, and I liked it so much I went searching for the source. The original is, apparently, old enough that the source is unknown, but it's still accurate today:

Reality is the murder of a beautiful theory by a gang of ugly facts.

Theory and reality are only theoretically related.

In theory there is no difference between theory and practice.

In practice there is.

I may make this the new official motto of TSM!
