We’ve all done it.

It’s way past your bedtime. Maybe you find yourself shopping online and then you buy … THAT THING. You know, the one that makes you say, “I can’t believe I bought that.”

We’ve opened up our own museum of regret, and we want you to add yours. Check out our Tumblr at icantbelieveiboughtthat.tumblr.com. While you’re there, leave us a story and a picture of the purchase you regret most.

Each week, we’ll pick our favorite entry and feature it on our show.

To get the ball rolling, here’s mine:

It’s a lithograph … I think? A big canvas print of a panda, holding six shooters, on a rainbow backdrop.

It came from the internet … and there might have been some wine involved.

That’s all I’m sayin’.
