Another one from Dutch:

"Knappe kappers kappen knap, maar de knecht van de knappe kapper kapt nog
knapper dan de knappe kapper kappen kan."

/knAp@ kAp@rs kAp@n knAp mar d@ knExt fAn d@ knAp@ kAp@r kApt nOx knAp@r dAn
d@ knAp@ kAp@r kAp@n kAn/

In English (as literal as possible):
"Skilled barbers cut skillfully, but the assistent of the skilled barber
cuts even more skillfully than the skilled barber can cut."

Note: "knap" in Dutch can both mean "skillfull" as well as "handsome".
