It’s early, the work week is just beginning and everyone’s got a bit of a Monday grump going on more than usual. It might be the weather, or it might have something to do with the appearance of Tardar Sauce [sic], the notorious Internet-famous "Grumpy Cat" of the blog of the same name, on The Today Show over the weekend. Take note, other people with weird-looking pets looking to exploit their Internet popularity. You can get on a pretty major daytime television program! 

The notoriously sour-faced feline appeared with her "pet parents" (at The Today Show, they don’t like to use the word "owner") Tabby (no, really), Bryan and Crystal Bundesen, who explained the cat’s sudden rise to fame and its mostly having to do with Reddit because of course. As for the appeal of her expression? "We think it’s because she looks so grumpy that you can’t help but be happy when you look at her," Bryan Bundesen told The Today Show. "She’s like a stress reliever."

Bundesen assured the crowd that Grumpy Cat is actually quite docile and playful despite the less-flattering brand to which she is attached. The Bundesens also hawked some Grumpy Cat merchandise (with some proceeds going to animal rescue charities), including Christmas cards, mugs and t-shirts in case you’re still looking for something for the slightly-unhinged cat lover or full-time Redditor in your life. 

Not to be outdone by his wildly popular Internet-famous cat counterpart, Lil Bub will grant an exclusive, tell-all interview to Katie Couric to air later this week. Watch Tardar Sauce’s appearance below.
