April Fool's Fun

When my 9 yr. olds get home from school, I am telling them that they need to brush their teeth and then get in the van to get to a dentist appointment. They will be shocked a bit because I always let them know about dentist and doctor appointments ahead of time. I will tell them that I completely forgot to mention it but that their dentist needs to see them again even though they were just there 3 months ago. (I am pretty good with putting on acts and surprising them.) Their dentist is only a few minutes away and instead of driving there I am going to pull into Baskin Robbins for a special after school ice cream treat!
I couldn't say something that would actually cause a huge disappointment such as saying I am pregnant like Rachel mentioned below. My daughter has always wanted me to get pregnant again and to say that I was (even for only a minute) would make her very upset to find out that I really wasn't pregnant. She wouldn't probably be so made at me and I want it to be fun!

Now my kids don't mind if what I say is false and it turns out to be a relief. An example of this is when I set the clocks early by 30 minutes in the morning on April 1st last year and they were telling me to hurry up because they thought we needed to leave for school. I said.... "Oh, I just need a few more minutes" They don't like being a minute late for anything so they began to get worried and said, "PLEASE mom hurry up and get your coat on." I replied, "Why??? It's only 8:20 April Fools!" They LOVED that they had 30 minutes to play and I let them play their Nintendo DS's before school.
Have fun!

A classic prank for little kids is to glue a coin down on something/somewhere. They'll try forever to get it!
Your kids are still pretty young, so it can't be too harsh or emotional.
Mine are 6 and 8 (closer to 7 and 9). They are off for Spring Break starting on Thurs, so no school on Fri the 1st. I'm thinking of waking them up for school and acting like everything is normal! We'll see how long it takes them to relize it - We walk to school and I'm prepared to walk them over if they haven't noticed yet!
I was also going to unplug the tv and act like it's broken.

I'm planning on putting these in my kids lunchboxes this year....

Green eggs and ham, get out the food coloring and be sure to read theme the story the night before they go to bed. LOL

I posted this question a couple days ago- I have been doing pranks for years and it's getting harder to think of any! Mine are older and don't fall for it anymore :(

Here are a couple I have done:

I snuck in their bedrooms and marked their arms/legs with dots and told them they had chicken pox!

I made cupcakes with colored icing, that were actually meatloaf and mashed potatoes. There are some really cute food pranks - try family fun!

I also melted a candy bar in my toddlers diaper and told them I had to taste her poo to see if she was sick. I licked the chocolate in front of them. They almost threw up - priceless ( they were about 3 and 4, then).

I've faked running out of gas in the car.

I got some good responses - I think I'm going to put newspaper on my kids doors, so they have to "break out". SO much fun!!

Have fun!!!!

Last year I made the mashed potato cupcakes for dinner with a pudding and candy pot pie for dessert (family fun website). I also opened their chip bags that I send at lunch and switched the contents. So when they opened the cheetoh bag it was actually full of doritos. I just taped up the end and they didn't notice. I like the idea of changing the clocks to give extra 30 minutes in morning.
