Professor Heine sends the princes on an assignment to investigate rumors of a criminal in the palace, and the truth shocks them.
Your jokes are terrible.
.نكاتك فظيعة
Deine Scherze sind nicht lustig.
Tus bromas son terribles.
Tus bromas son terribles.
Tu me gonfles avec ta blague.
Le tue battute non fanno ridere per niente.
As suas piadas são 
realmente terríveis.
Шутишь ты, конечно, ужасно.
