Redundant Language for thought January 12 2010

Just thinking about those funny redundancies (tautology rhetoric) in English that we use or hear everyday?

ATM machine M=machine, PIN number N=number, UPC code C=code, RAM memory M=memory, OR chai tea, chai=tea, ramen noodle, men=noodle, and last but not least, washi paper -shi=paper

Can you add to this list?
