Hehehe... YES! AND A LOT OF THEM, I'm sorry to say.

Read over the U.S. Customs page on Prohibited and Restricted Items @ http://www.cbp.gov/xp/cgov/travel/vacation/kbyg/prohibited_restricted.xml

Canned goods are always allowed up to a point. I remember on one return-flight back to the USA I'd packed a suitcase nearly full of about 30 cans of anchovy-stuffed-green-olives and 20 bricks of Spanish coffee. I was in Spain-Heaven for about 3 months.
