Game show contestants give the most hilarious answer

As long as there are game show contestants, these types of videos will never be extinct.

Apparently two heads aren't always better than one as a mother-daughter team on Australia's version of "Who Wants to be a Millionaire," had an epic fail as the two of them combined had no idea that a Thesaurus was NOT a dinosaur.

Which of these is not a type of dinosaur?

A. Brachiosaurus

B. Stegosaurus

C. Tyrannosaurus

D. Thesaurus

Apparently neither one of these ladies have seen Jurassic Park, as both of them were stumped beyond belief as to what the answer could have been.

Watch the hilarious scene unfold in the video above.
