You can, but the only smilie your computer will properly create is a kissy lips face. Enough said.

I wish my internet could download stuff faster.

Your internet downloads everything faster---including viruses.

I wish I could dance.

You can dance amazingly, but now you can't stop dancing.

I wish I could go on a hike.

You get to go on a hike, but you are so busy admiring the fall foliage and looking out for any wildlife, you step in a hole and twist your ankle .

I wish I could travel anywhere of my choosing instantaneously...

You can, but whenever you use that power, the location where you were is destroyed so that you can never return there.

I wish I had more wishes.

Kazaam! You do have more wishes. But be careful about what you wish for. Those thoughtlessly wasted wishes are the only ones that come true.

I wish I could be young again.

You are young again, but of course everyone else you know continues to age and you realize that it's not fun to go back since you can't relive all the same special moments.

I wish I could have wonderful dreams each night.

Your dreams are now so blissfully sweet that waking up and being in the real world is a complete pain, even when you're at Disney World.

I wish I only needed 4 hours of sleep per night.

You only need 4 hours of sleep each night, but now you need 10 hours of sleep during the day in addition to the 4 hours of sleep in the night.

I wish that I could find my family's remote control for the television.

You find the long lost remote, but when you go to finally watch something, the tv is missing, which appears to be a much greater problem and also deems your remote useless.

I wish the best moments in life didn't go by so fast.

You can slow down the best moments and savour them, but you also have to slow down the worst moments.

I wish I could do NaNoWriMo this year.

You can do NaNoWriMo, but, for some reason, your NaNoWriMo story must be about giant kittens who want to take over the world, monsters made out of cottage cheese, and a short fat guy named Joe who is armed with a pizza eating device. Because of that, your story turns out to be terrible, and your story is destroyed with no trace.

I wish I could make a really good thread on NarniaWeb.

(I think I might read a story with that summary if it was funny... )

You make a really good thread! People love posting in it! It is about cures for hiccups.

I wish for a fresh, hot, cinnamon roll with lots of sugar glaze.

Wish granted! Unfortunately, there is so much cinnamon and sugar glaze on the roll that you can't eat it without feeling sick afterwards.

I wish to build a giant, glowing snow igloo this winter.

You build one but it only glows because of a freak nuclear accident... which unfortunately also affected you in less pleasant ways

I wish I could have cheese ravioli once every other week.
