In one gag, Peter hides among a herd of goats. In the movie A Million Ways To Die In The West, Seth MacFarlane hides among a herd of sheep.
Words from the book Goodnight Moon of Chernobyl:
Goodnight Chernobyl moon.
Goodnight radiation house.
Goodnight melted phone.
Goodnight glowing milk.
Goodnight bleeding grandpa's eyes.
Goodnight two-headed cat.
Goodnight nobody.
Goodnight blocks and blocks and blocks of nobody.
The end.
