Lightning McQantas

This is Lightning McQueen, a character from the movie Cars. Liem has watched this movie maybe twice but still doesn't quite understand the story. He does know that racing cars that are going fast go "NNNNGGGGIIAAAAOOOOO!!!!". He also knows the name of the red car is Lightning McQueen. However, he starts to make up names for the other cars.... The green car he calls "McKeen" and the blue car "Lightning McQantas". Don't know where all these come from...
