Can Someone Fake a Coma?

Could someone fake a short-term coma, say for a few hours at tiniest? Or would there be medical and physical evidence that they be indeed awake?Can Someone Fake a Coma?
I've seen relations try. I must say that it's vastly entertaining and breaks up the monotony of my busy hours of daylight.
We have ways of finding out if someone is fake a "coma". What's so funny about it is that these methods of discovery regularly end up self rather embarassing to the "comatose" character.
I won't tell you what those ways are...I despise to give away tricks of the trade.

No you can't insincere a coma.
read: sternum rub!
vit happened contained by artemis fowl. but really no. you aare so out of it in a coma. no muscle movement and no voluntary movement at adjectives. no pain responses any. kinda hard to misrepresent.
why did you do sumthin to your little brother and want to know what to tell your parents? lol.
no u cant insincere it you still react to uncomfortable stimuli such as yelling. you dont bawl if ur in a coma
