Walmart is set to annoy the hell out of you during NBC's live broadcast of the Sound of Music tonight. 

As Brian Steinberg of Variety reports, the big-box leviathan is a presenting sponsor of the show, but that's not the worst of it. It appears Walmart will air ads created by NBC, featuring songs from the musical, timed to air right after the songs are performed in the production. So, for instance, in the commercial break after Carrie Underwood teaches the von Trapp kids that "Do-Re-Mi" ditty, that song will play again, this time for the purpose of selling Walmart products. 

All five ads, according to Steinberg, will feature the real-life, 12-children-having "Brooks family of  Gardner City, Kansas," who will perform tasks that correspond to the music, all featuring the finest in Walmart consumer goods. The "So Long, Farewell" ad will try to shill electronics. 

So watch out for high levels of Walmart-related frustration tonight, as viewers collectively try in vain to get "My Favorite Things"-branded merch out of their heads.
