The Earl of Lemongrab debuted in Adventure Time's season three episode 'Too Young' in 2011 on Cartoon Network, created by Pendleton Ward and voiced by Justin Roiland. His shrill 'Unacceptable!' catchphrase quickly became a fan favorite, with compilations of his tantrums earning millions of views on YouTube. The specific castle rant spread through meme edits, gaming rage clips and TikTok reaction videos in the mid-2010s. It endures because Lemongrab's petty authoritarian meltdown is the perfect over-the-top stand-in for everyday disappointment.
