I will eat a little bit. Unlike most people, I don't pig out on T-day. My stomach is so small.
But I will probably spend most of the day watching movies on my 52" HD Big Screen TV with the PS3 hooked up to it.
That is mostly our plan as well, except we have two football games to watch. We just got a new Samsung 59 plasma set (to replace our smaller 47 incher LCD, which has been banished to our bedroom. )
