A pair of contestants on Australia's "Who Wants To Be A Millionaire" has become instantly viral after failing to answer a seriously easy (and obvious) question.

Most Millionaire Hot Seat contestants play the show individually, so the mother and daughter duo, named Tania and Christina, already had a huge advantage over others by having an extra brain on hand.

Hailing from Western Australia, the duo clad in matching leopard print outfits were asked which of the given answers is not a dinosaur: Brachiosaurus, stegosaurus, tyrannosaurus, and thesaurus.

After the $200 question was posed, the Australian cooking reality show, "The Hotplate," contestants looked very perplexed. Christina said, "I think we'll pass because I'm not sure if it's D [thesaurus]." Meanwhile, Tania didn't even seem to ponder for the answer.

Host Eddie McGuire then asked, "Are you sure?" The two then confirmed that they will be passing on answering the question.

Eddie McGuire even asked the pair a couple more times if they really wanted to pass on the easy quiz query. The two weren't able to find out what the answer (it was thesaurus, obviously) was, as their game show stint ended there.

Although Tania and Christina miserably failed, French father and son duo Pascale and Philippe were able to garner $1000 on the same night. 

Pascale and Philippe ended their streak when they weren't able to correctly answer a question under the car category.

The question was: "'Celerio' is a make of car from which manufacturer?" The choices were Mazda, Hyundai, Suzuki, and Honda. If Pascale and Philippe had answered Suzuki, the two would have brought home at least $50,000 just for that last question.

On the other hand, there was also Aaron and Vanessa, a Sydney-based couple who had a bit of tension during their game time.

Chef Aaron didn't consult his girlfriend before answering the question, "A person who has to admit they were wrong is said to 'eat' what?" Eddie McGuire even noted, "Not much conversation going." While Vanessa, seemingly irritated, answered, "I know, geez!"

She then laughingly said, "I didn't know but it would've been nice if you consulted me but anyway!"
