LOL. I love that "piece of your brain" line. Also when she is trying to find her glasses and they are on her head but she has her hearing aid turned off. Basil's frustration at trying to tell her is priceless.
Ah the German episode. Always reminds me of my honeymoon. My wife and I went on a tour that consisted of us and 8 germans. My wife was getting so pissed because I just kept whispering " Listen, don't mention the war! I mentioned it once, but I think I got away with it all right."
Also from that episode I love this little bit
Basil: Is there something wrong?
Elder Herr: Will you stop talking about the war?
Basil: Me! You started it!
Elder Herr: We did not start it!
Basil: Yes you did — you invaded Poland
