my sister has a brazilian exchange student living at her house and he is supposed to write a story for English using two examples of irony. The story is supposed to be about a guy in prison.
Can you give me some simpler examples of irony? I tried saying “a fingerprint expert sent to jail on fingerprint evidence” but he didn’t get that, can you give me some others? I am just drawing a blank…?
A guy convicted of poisoning his wife is given work as the prison cook.
Here is a real one that I heard about.
A world renowned cardiologist was found dead in his hotel room with a half-empty box of antacids next to him. His death was determined to be caused by a heart attack (many people who don’t know better think that their heart attack is just indigestion).
A politician who campaigned on a platform that emphasised harsher penalties for a certain crime is convicted of committing that crime and is sent to prison for it.
Here is a similar one and it is a swear to God no urban legend. I used to work at this fancy hotel in New Orleans in college. We did catering for weddings and events and things. I got hired quickly and the manager told me that he was new himself. When I asked what happened to the old one, he told me that the old events manager was hosting a dinner for a cardiologists conference. He stood up to give the introductory speech in front of all the doctors and collapsed on the floor in the middle of it. He was pronounced dead a little while later. He suffered a sudden heart attack and none of the doctors could save him. I heard that they had real trouble getting anyone to take the lead at all. The man was 35 years old.
That one borders on the irony/tragedy line but it is easy to understand.
A congressman who was in charge of a committee dedicated to stop online preditors of minors goes to jail for soliciting sex, via instant messaging, from a sixteen year old boy
Nobody can quite agree on the “true” definition of irony. I think this is pretty ironic.
Go for the classics – The Gift of the Magi, the O. Henry short story about a poor couple who try to give each other Christmas gifts. The wife has beautiful long hair, which she cuts off and sells and uses the money to buy a watch chain (I think) for her husband. Meanwhile, the husband has sold his watch to buy his wife combs for her beautiful long hair. It’s possible the student has encountered that story in school, so perhaps it will make the irony click.
Rain on his “wedding day.”
Oh man, you totally stole my example! 
My mom once called me a sonofabitch, would that apply?
Your intensive studying for exams in fact kept you up so late that you couldn’t concentrate during the actual test, and you did worse than you would have by studying less.
Some loud mouth radio personality who calls for stiffer penalties for drug criminals is later found to be addicted to and illegally abusing perscription drugs.
Irony? A guy in prison? Try J.P. Sartre’s The Wall. 
Any hetrosexual who has been married and divorced more than once who complains that gay marriage will destroy the institution of marriage.
The guy in my school district trying to ban Farenheit 451.
A brazilian? Wow, she must have a LOT of rooms!
A book in the prison library with a ‘get out of jail free card’ stuck in it as a book mark.
Whenever I think of irony, I get the image of Jim Fixx, a big proponent of jogging in the 1970’s, dying of a heart attack.
True simple irony, rather than cutesy twists of fate?
An imprisoned nun.
A prisoner finds that the prison food is better than any he’d ever eaten as a free man.
A man learns he feels safer among his fellow inmates than among those in his social circle outside.
A prisoner and a guard fall in love.
