"Isn't it ironic?" In the case of the cover of Alanis Morissette's iconic '90s song covered on The Tonight Show by Jimmy Fallon [1], Morissette, and Meghan Trainor, it's not ironic — it's just hilarious. The "Jagged Little Chicks" cluck the tune of the seminal song, and if you are not made of stone, you will giggle, and you won't be able to help it. And that's OK.
