Let's see if I can get some extra points here

.
Sometimes I use "You bet", which is not very exciting, but I use it in English when talking to other Germans (puzzled looks guaranteed).
I love, love, love to use "Tent don't look right", no matter what kind of thing doesn't look right (but only to my husband who knows).
I attend an English conversation circle, meeting other people who can speak English to get more practise. And there I sometimes use Brokie-isms. For example I called one of my daughters a "lively little gal" (what she is indeed) and once used the "dumbass mules".
I use "Tell you what", translated to German, more often than I did to before BBM.
But I can't count the times adequate Brokie-isms pops up my mind during everyday conversations and I don't say them.
