The Cavematsus make another appearance, and the sextuplets try to figure out what's bothering their father.
I want to have a pervy relationship 
with your mother forever!
أريد أن أحظى بعلاقات
منحرفة مع والدتكم إلى الأبد
Ich will auf ewig mit Mutter
den Knusperhüttenwalzer tanzen!
Je veux que cette flamme érotique
continue de brûler entre nous !
Voglio continuare a fare le cosacce 
con vostra madre finché campo!
Eu quero ter um relacionamento 
erótico com a sua mãe para sempre!
