Segmeowtation Fault (seg-mēau'-tā-shən fôlt)
n. 1. The inevitable error caused by a cat walking across a keyboard.
2. Occasional musings, rants, and cats from a Midwestern engineer's desk.
This applies to dogs, too: Just change "tap" to "toilet."
Enjoy some comics better than mine: BOASAS, Diesel Sweeties, Doctor Cat, Doodle for Food, The Oatmeal, xkcd
