Lots of Limericks (three dozen, to be exact). For $9.99, you can either cheer up one friend (which, as eBobb sees it, is the purpose of the limerick), send a dozen limericks to three friends, or one limerick to three dozen friends. Hey, is this the godfather of all cheap . . . errr, economical gifts, or what!?! As for the cheering up part, here's a sample from eBobb's Lots of Limericks::

Limerick# 29
Though her kiss surely changed the frog's life,
The cost was emotional strife
For the quick change in size
Gave him such a surprise
That he jumped up and stepped on his wife.
