Bubble Watch
By Kate Ashford

(MONEY Magazine) – Retailer T-ShirtHumor.com has struck a nerve with its $20 "Mr. Hou$ing Bubble" tee, the site's fastest seller ever. The real estate industry wasn't amused: The news site Realty Times suggested that if there really is a bubble, products like Mr. Hou$ing Bubble could help pop it. Wharton finance Prof Jeremy Siegel, himself not a big bubble believer, hints that the reaction sounds a little...bubble-ish: "It surprises me that the industry is so sensitive. Maybe they're worried themselves." --KATE ASHFORD
