Ben Who?

Ben 10 Omnitrix F/X; it's all the rage this year;
For boys who watch the cartoon it's a must-have, I hear.
It's black and green and really cool;
A supply shortage I fear.
Ben 10!

The stores are sold out, only ones are waiting on Ebay,
For three times the retail price you can own one today.
Remember PS2 and Elmo,
Hurry, don't delay!
Ben 10!

UPDATE: HolyChow and my algebra buddy (nephew) found one! Score!
