That would do it.

For those of you who are confuseded, here's a cycle of how it goes;

Ping me
I roll a 20-sided die and post the result. If it's above a certain number, you find an egg. If it isn't, you don't.
If it IS a successful roll, I'll use random.org to bring up the randomized list and tell you what egg you found! Complete with little (probably crappily-done on my computer) picture of the eggie.

Since my own D20 fell off the desk when it rolled, I'm going to test the Mene method! XD

The 20-sided dice lands on 5

Edit: IT WORKS!!! YESSSSS!
