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