Up until recently I had "Target" and "Splish Splash" listed in my past experience. Not for lack of other experience, I think I was just being lazy about taking it out. I think that's pretty ridiculous. I've decided that a good practice is that if you wouldn't list it in your resume, don't list it on your LinkedIn profile. I've also seen a couple people who were graduates of places such as the "School of Hard Knocks" and the "University of Being Awesome". You know, prestigious institutions.
