Stamps for a laugh

Here is what happened that one time I went to the post office and the lady made me put 16 stamps on a small envelope.  Seriously?

This is the back of the envelope...

Today she gave me 5 stamps for a postcard.  Are you kidding me?  I want to make a formal complaint, but to who???  Apparently you can stack the stamps as long as you can see the value of each.  Well, I used some glue and stacked those babies up.  Mom & Dad, hope the postcard makes it to you :)
