You can just give me a cut 
when you make it big.
Ihr könnt mich bezahlen,
wenn ihr fett Karriere gemacht habt.
Me pagarán cuando sean exitosas.
Me pagaréis cuando tengáis éxito.
Vous me paierez plus tard.
Mi pagherete quando vi sarete affermate.
Podem pagar quando alcançarem o sucesso.
Заплатите, когда разбогатеете.
