Idea idea

The other day, I read this funny man's comment on someone's blog somewhere in the blogosphere. He mentioned about a top ten list of something that kinda sound like this:

You know that you're in the 20-30 age group when...
-You've received a hand's full of friends' wedding invitation.
-...
-...

So, am just wondering. Do you guys wanna participate in the creation of this top ten list? Please, jot down ur idea on the commbox or shoutbox, of course u could write more than one point. Then, we all can sort of do some editing, rewriting, and decide the proper placement of each sentence on the list. Just to make it even funny. What do you guys think?
