O.K. lets try this again...
A man is dead in a room with 53 bicycles.
Under what circumstances did he die??
He was murdered because he was cheating at poker. They were bicycle playing cards and he had an ace up his sleeve. Also, 42 is the answer the ultimate question and muffins are surprisingly high in calories. 
Damnit Serissa!! you had to spoil it!!! Play in someone elses sand box!! 
If you don't want me to answer a riddle you have to specify whether or not you really want an answer!
Or, rather, "If you've heard this one before, don't ruin it."
Having said that, don't ruin this one if you've heard it before.
You're dead. Sucks to be you. What's worse is that the afterlife is very confusing. You're now outside the gates of heaven and hell, and they're right across from each other. Each gate is guarded by an angel. One can only speak the truth, and one can only speak lies. You, yourself, are only allowed one question, and then you have to pick which gate you're going through. What should you ask?
"Is she gone yet?"
