That's the last time I have Taco Bell for lunch at work. Now I'm going to have to do some ninja pooping.

Stage Ninja

A wannabe roadie. Usually has the clothes and the tats but no real skill. Constantly boasts about where he has worked or how long he has been in 'the business'. Criticizes others openly but never offers an opinion of his own. Often carries a large quantity of useless keys to look important.

Get rid of these stage ninjas and get me some stage carps who know their stuff
