Unlike dinosaurs, game show bloopers that make you shake your head will never go extinct.

Meet Tania and Christina, a mother-daughter team who competed and embarrassed themselves on Australia's version of Who Wants to Be a Millionaire when asked the following question:

Which of these is not a type of dinosaur?

A. Brachiosaurus
B. Stegosaurus
C. Tyrannosaurus
D. Thesaurus"

Do you know another word for "duh" because neither woman knew the answer, which is a shame, since the crowd actually chuckled when thesaurus was read. Right there, they should've had an inkling of the answer.

Instead, mom and daughter elected to pass on the question and go down the road of internet infamy for their lack of knowledge.

They say two heads are better than one, but in this case, that is most definitely not true.
