Lesson of the day: Don’t give Kanye West career advice.

Apparently that’s what Zappos CEO Tony Hsieh tried to do during West’s recent Vegas visit, when the pair toured Downtown during the Life Is Beautiful festival, and West wasn't exactly receptive.

In a Monday podcast with Bret Easton Ellis, ’Ye ranted -- as only 'Ye can -- about a little chat they had that turned sour.

"I got into this giant argument with the head of Zappos that he's trying to tell me what I need to focus on. Meanwhile, he sells all this sh*t product to everybody, his whole thing is based off of selling sh*t product," West said. Oh, to be a fly on the wall during that conversation.

In a comeback as classy as it is scathing, the notoriously impassive Hsieh responded today with a new item listing on the Zappos website for “Sh*t Product,” accompanied by photos of a toilet and the following description:

Interested in buying sh*t product? You've come to the right place! Here at Zappos.com, we happily sell sh*t products to everybody! This is the throne, everyone has been watching. Whether you're #1 or #2, your clique will show no mercy, even in Paris.

The perfect gift for the man who has everything.

Requires lots of "focus" for most productive use.

Considered a "safety zone" when in arguments.

Makes giant arguments seem much smaller.

Caution: Do not place our Sh*t product near any fans.

Avoid storms.

Your move, Yeezy.

In the meantime, we have a feeling this means he won’t be relocating his G.O.O.D. Music label to Vegas after all.
