This joke works way better out loud because it's funnier to yell the punchline...

[umasenvy]

Two muffins are in a muffin pan. They get put into the oven. After a few minutes one muffin says to the other "Boy, it sure is warm in here." Then the other muffin says...

"HOLY SHIT!!!! A TALKING MUFFIN!"
