Having a bad week? Take heart. You're most likely not as dim as Jacob Walker and Joseph Velarde. The two Arizona-based geniuses put up a Craigslist ad that said they were willing to trade an iPod touch and a good amount of pot for an Apple iPad.

"i am willing to trade my 32 gb ipod touch 3rd generation and a quarter of DANK. blue dream straight outta cali," according to a copy of the ad that was posted on Edible Apple. "the ipod is in PERFECT condition. not one scratch. it has been in the case the whole time and has never had screen cover removed!!!! let me know!!!!"

The ad included a photo of the iPod touch next to the pot, on a scale.

Flawless plan, right? Too bad it was police who responded rather than an iPad-owning marijuana enthusiast. Police in Gilbert, Ariz. saw the ad and set up a meeting with Walker. He and Velarde, both 20, were arrested after handing over the pot.

Both face posession and distribution charges.

The real question, of course, is whether this would be a fair trade? A 32GB iPod touch sells for about $250, while the iPad pricing starts at $499. I'm not really up on my pot pricing, but a helpful commenter on the azfamily.com site said that that amount of pot would likely sell for about $100, so you do the math.
