Post Malone's Acoustic Cover of Green Day's "Basket Case" Is Awkward as Hell
Say what you will about Post Malone, but the man is absolutely full of surprises. When he's not jamming with a mariachi band or surprising Rich Chigga with a gospel choir, he's developed one hell of a ridiculous live show. Along with a botched stage dive, his concerts have featured another relic of the '90s with a Green Day cover.

Last week, while performing in Maryland, the rapper took a chair and tried his hand at Dookie standout "Basket Case." Despite the sparkly silver guitar, the cover was more suited to a campfire than a massive audience.

Regardless, Billie Joe Armstrong felt the love and opted to share the performance on Twitter, writing, "hey this is pretty cool!" Is it, Billie?
