o_O WT* Could somebody explain this?

Do you remember this from the Buon San Valentino - Aftermath?

PANEL 1 (TOP)

Austria:
"What were you thinking, trying to practice on me?!"
"France sent some vulgar book over..."

PANEL 2

Austria:
"Why do you always lose your head when it comes to romance! So foolish and (blah blah)..."

Germany:
"I'm sorry..."
"...BUT YOU DID TAKE OFF YOUR PANTS ON YOUR OWN."

PANEL 3

Austria:
"Unlike you, Austrians are upright citizens."

Germany:
"That's what you call 'upright'?"







I don't know what to think of this.

I guess, it's just, Austria... is really noble to be of help to others. What do you think?
