from his comments:

"Here's the fake dialogue that I wrote for each language. Any similarities to real words are purely coincidental:

Chinese:
Wo jiao piang xie? Da tian jiang ger pang ma! Xie ming ma chen ge la. Ne fan de shun weng she.

French:
La maricot de la francheuse est la botonnaisse et la botteneuse. Tot pa plattannie? To pa plattonisme. Hein? Noreune les oides terrianal.

Italian
Della ma groppoforma di papaligia. E fangelli ma trima, costo mosso: agalla mosto. Pi trima, pa trima.

Russian:
Yuvesh boytnik, graznik -- bohpamoshet badnya. Zet yon a yevleskou groynik. Lepni zet bevchenkski.

Spanish:
Los jungames pala muenos. Copa del jumos pi zampistas: pi querames, pi pleyames, pey gustarañes. !Pi taballyama, pi codo¡

German
Das grumfph ist peine keirschminte, peine greutzenschtepp. Greutzenschtepp ist peine schweirmarke.

Japanese
Gore no ho kakkamatsu, gun makahashimu jo. Kotero unitasu hanashi ma? Kaitu moroka. Hun."
