Hah, get it? Tongue:
as in language, and also as in the muscle in your mouth;
implying ever so slyly that they're better at oral ***!
Hah! So punny!

It doesn't translate into German very well; tongue doesn't mean language in German;
but, I did it anyway. New connotations for old denoted words!

True wisdom sometimes dwells within the most tasteless of humour.
