If you are an Asterisk user and have some time to kill, go check out all the sound files located in:
A few good ones are “Weasels have eaten our phone system”, “They have been carried away by monkeys” and “The office has been over run with iguanas”.
There is also “To infuriate our tech staff with your obvious questions press…”, “You could lose a few pounds!” and “Will you marry me? Press 1 for yes or 2 for no.”
This is my personal favorite
"Try to spend your time on hold, NOT thinking about a blue eyed polar bear."
And of course, bringing me flashbacks from the days of Zork
"There is a shiny brass lamp nearby."
