Conversation #1:
Igor: Nikita, how are you feeling?
Nikita: I'm feeling that this (obnoxiously loud) truck should be louder.
Conversation #2:
Igor likes to tell Nikita that the eyes of Bob the Builder make him look drunk. So, Nikita colored in the eyes, and told Igor that Bob the Builder now has glasses, so the flies won't get into the eyes. Apparently, Nikita thinks the word for drunk ("pahd-mukha") has something to do with flies ("mukha").
