A coma is a state of prolonged
unconsciousness, which can be caused by one of many, many things. Many people believe that even if a person is in a coma,
s/he can still
hear you if you speak to him/her.
"Hey there, Grandma. I hope you wake up from that
dreadful coma soon. I miss your cooking--"
*Nurse leaves*
"I'm going to spray some whipped cream up your asshole, and THERE'S NOTHING YOU CAN DO ABOUT IT!
Haw haw haw!"
