Damn. Spent too much time away from the page and got post-jacked.
Poof! Wish granted. You've got a transporter. You can go wherever you want and get back in the blink of an eye. Unfortunately, as established by StarTrek:TNG, every once in a while things can go wrong with the complicated beast. So, at least once a season (or more if the writers are blocked) something weird happens to you or a friend using the machine. Well, now you've got your molecules mixed up with a dog.
Your friends have all gotten used to you trying to hump their legs, but you can't go anywhere fancy anymore. It's really hard meeting new people and making a good first impression. You can explain away the dog breath, but it's pretty disconcerting watching you lick your own .... hole at the most inopportune times.
You're hoping you can hang on as long as the year 2361, when a young Geordi La Forge is able to figure out how to set everything right again.

Granted.
However, the estate of Gene Roddenberry sues over "intellectual rights" leaving you penniless and homeless, vapless.
I wish we could find the house we want for sale at an affordable price.
Poof! Wish granted. You get a really sweet deal on a house at a foreclosure sale. Unfortunately, just before you take ownership of the house, you find the evicted tenants have done a little "redecorating" with sledgehammers. Structurally, the house is still intact, but there isn't much left of the walls and floors. Whatever remains has been used as a bathroom by countless dogs, cats and possibly elephants? (by the look of it -- ewwww!).

I wish I had a really good carrying case for my collection of PVs.
