Hee hee thanks for reviving an excellent memory of being in French high school taking German, and when we learned a cuckoo song, we all sang Cocu, Cocu (cuckold, cuckold) and the teacher, who was neither German nor French (nor American, as I was, nor African, which was where we were), had no idea what we were doing, but you could tell *she* could tell we were up to SOMEthing! Man, those were the days...
