A man is dead, surrounded by 53 bicycles. How/why did he die?
Was it an airplane cabin that crashed?
Sorry about posting so late on the other airplane one.
This one however, I’d say that he was in the tour and shooting up on EPO, died from overheating and caused a crash. But that’s too plausible.
Do the bicycles have two wheels and handlebars?
erm… no.
Are they a deck of cards?
More properly, Bicycles.
The scene: a sawdust tavern. Dark, armed men fill the room. Whiskey flows freely.
Four men sit around a table littered with gold coins. One, wearing a black hat, spits into a spittoon and slides three ten-dollar pieces into the pot. Two grunt and fold. The fourth looks warily into the first man’s eyes and pushes three of his own coins to the middle of the table.
They throw down their cards. The first man has five spades. The other has the fives of hearts, diamonds and clubs and the aces of hearts and spades. All eyes shoot again to the first man’s hand. The ace of spades is included. All four men jerk to their feet. Hands hover near revolvers. The man in the black hat overturns the table. Cards flutter through the air and coins roll across the floor. He draws and shoots the cheater dead.

Get it? Bicycle playing cards.
You sure? I thought I saw a documentary on the nature channel about an elephant named “53 bicycles”. That was gonna be my guess. 
Ooo, fun fun. Inasmuch as Check6 got the last one, I’ll make my entry into this thread the next question:
A man walks into a house. He turns on the light. He turns on the radio. He shoots himself. Why?
Check6 is right. (Love the little backstory!)
donkeyoatey was probably on the right track, though.
'cos he’s making a nude dance video of himself and he needs light and music ???
Nope, nice guess, though. Prolly an omission in the telling. By “shoots himself” I did, in fact, mean suicide. Nothing tricky there.
a. Man walks into house. So he’s not in a wheelchair and therefore not terribly injured or anything else like that, so it’s doesn’t appear to be desparation.
b. He turns on the light. Depends on whether he has an affinity for ‘turning on’ the light? Unlikely, but maybe he’s a bizzaro, weirdo, that likes fantasizing about lighting fixtures. Ahhh, but maybe the light is not working ???
c. He turns on the radio … is he hearing the ‘duck and cover’ warning???
d. He shoots himself, 'cos there is no light, the radio is saying your arse is soon gonna be melted into your carpet, 'can’t take the 100 year nuclear winter and takes the quick and dirty way out ???
Still nope. “Turn on” is meant in an entirely switch-flipping or dial-turning (or equivalent) manner.
OK, let’s try another tack.
He walks into a house (question over whether it is his or not, but nevertheless I press on). He is there to kill someone.
He turns on the light. Maybe to see whoever it is he wants to kill.
He turns on the radio. Maybe a little music will put him in a better mood.
He kills himself. He is actually the local radio DJ, he has put on a CD at work to cover his absence and the CD is skipping tracks. He realises that no-one will believe he was actually at work, and to take the easy way out he shoots himself.
Nope again. He has every right to be in the house, and he is alone.
Did he electrocute himself turning on the radio?
Nope. Light and radio work fine, no electrocution of any sort, our guy is perfectly dandy right up 'til he offs himself.
He sees something horrible (murdered family?) when he turns on the light. Then he turns on the radio to confirm it. Upon finding out it’s true, he kills himself.
Is he blind?
