Mac Lethal brought us Alphabet Insanity in 2014, in which he constructed a rap around the letters of the alphabet in order. Yeah, that was awesome, but now he's upped it a notch with a new version with all new words, and yes, he speeds it up as he goes along, getting through all the letters in less than two minutes. Just listening to this made me feel tired, but impressed. -via Geeks Are Sexy
