I've seen a few series I like post parodies of their usual material on April Fools and it turns out the series has the perfect thing. (It was either this, or do an actual joke and post the Kumoccho song from Mirumo de Pon)
Also called "Mishearinglish", the title is a play on the words English and "Soramimi" the word for when something you can't understand, particularly words in another language, sound like something you can understand. The opening to the second movie is partially that and partially translations of varying quality, give it a listen, it's wild.
