I found this disturbing and I said so. Still I don't find myself to be easily offendable or sensitive. I certainly wouldn't advocate boycotting Woot, shaming them, encouraging others to not buy from them ever, etc. And seriously, people who want to hurt others are not sitting around getting sick ideas from t-shirts.
I dunno, I have a dark sense of humor but I don't find this amusing at all. And before anyone jumps on me as being up-tight or morally hoity toity, let me just say, I know--I don't have to buy it--and I didn't. It's kinda like how I find Freddy Krueger disturbing and I just don't make a point to watch his movies. But if others want to watch them, whatever. That's their prerogative.
I did read those linked snopes articles too. I think it's not so much whether this has or has not happened or if it's common or rare, but the idea that it's feasible, at least for some of it. I think it's the possible things like the needles and the razor blade that really threw me to the "this is friggin' creepy" side. I think it could have been much better if as other suggested it was all complete nonsense weapons like cannons, nunchuks, cartoon bombs, or chainsaws in the candy.
I'm amazed not so much at how many people are intensely bothered by this to the point of even swearing off Woot over it, but more over how many people are bothered over the people who are bothered...It goes both ways. It's OK for someone to like this, and it's OK for someone to not like this. And not having the humor to like this doesn't make someone humorless, it just means their sense of humor is different. I thought we all went over this stuff with that one line unicorn shirt...*sarcastic eyeroll*
Overall a rather amusing thread going on here, far more amusing to me than the shirt anyway.
