The Staples Easy Button, the gift that says "I Hate You."
I should have posted this during the holiday season, but we were in Staples this weekend buying some cable and they had their "easy button" on sale.
I was trying to think why someone would buy it. Then I realized, it's a great gift to give someone you hate. You spend five bucks, give someone the "easy button," and you instantly tell them you despise them, without doing so overtly. You are telling them, "I know you have a stressful job that you hate, so the next time you are faced with a difficult stressful problem at work, just hit this button, which will say 'That was easy,' and instantly your problems will be exactly as stressful and unresolved as before, but now you will think of me and how much I hate you."
And you thought it was a useless product.
