Calvin and Hobbes by Bill Watterson for April 12, 1987
Transcript:
Calvin: "During emergency landing, replace dinner tray and bring seat to upright position. Extinguish all smoking materials." Including spacecraft, if possible! Out of fuel, the courageous Spaceman Spiff is forced to land on the distant planet Zok! The valiant explorer surveys the Zokkian landscape. Who knows what dangers lie hidden in the cratered terrain? Undaunted, Spiff sets out to find help! Miles later, it is evident the planet is completely uninhabited! Our hero is marooned on a lifeless planet! Alone on an alien world! Alone, all alone. Darn it, why doesn't anyone ever tell me when the lunch bell rings?
Wow he must have been pretty deep into his mind to not hear the shrill ring of the bell!
