Also, I am determined to start using alternative responses other than the stock phrases we are taught as students of German as a foreign language. To that end, I have already picked out one for "Thank You":

Kein Problem. Ich tu's aus meiner Buergerpflicht.

which in English means "No problem! It's my duty as a citizen."

If you can think of any (in German or English) that I should start using, please use comments or AIM and tell me so.
