Adele has already proven that she's the Queen of public pranks, but she's somehow found a way to top herself and fooled a group of unsuspecting Jamba Juice employees.

With the help of Ellen DeGeneres, who was telling the singer what to say via an earpiece, and a woman posing as an assistant named Simone, Adele successfully punked everyone into believing she was both a delusional diva and a deranged lunatic.

Despite the sheer outrageousness of the situation, Adele was game for whatever Ellen had to throw at her. From dumping the contents of her purse, including handcuffs and a lone Twizzler, onto the counter to eating some wheatgrass, she kept a straight face the entire time without faltering.

Emmy voters should consider this when making their nominations, somehow. It would certainly bring Adele one trophy closer to that coveted EGOT.
