Adieu mein kleine gartenoffcier

Mostly nonsense, but some of the parts of the Words in it make sense in either French or German.

Adieu - "goodbye" in French
mein - "my" (but not really in a grammatically correct form ... think "Me want eat" to get an idea in English of what's wrong with it) in German
kleine - "little" (but again not really in a grammatically correct form) in German
garten - "garden" in German
offcier -"officer"(and I'm not 100% certain it's spelled correctly) in French
