Don't believe in magic? Don't tell this baboon.
The little guy had his mind absolutely blown when a magician showed him a card trick at a zoo.
With the flick of the wrist, captured on video, a white card is seen vanishing in a man's hand, turning the baboon's bored-looking stare into a look of total disbelief.
When the magician makes the card reappear, the baboon again gasps at the sight while reaching out in an attempt to touch the card.
The entertaining scene was shared by American's Funniest Home Videos Tuesday but it wasn't immediately clear when or where it was taken.
Ian C. Colquhoun, a primatologist at the University of Western Ontario who viewed the video, said the baboon is clearly surprised by the trick but likely not angry, disturbed or stressed by the display.
"While the male hamadryas baboon unquestionably reacts to the sleight of hand card trick, I would not characterize that reaction as overtly, or extremely, aggressive. If it were, the baboon would have been prominently displaying his canine teeth, and the gape of its mouth would have been much greater -- what primatologists refer to as an 'open-mouth threat,'" he said in an email to the Huffington Post.
Colquhoun noted that the baboon's raised eyebrows and his hand-slap on the glass could be interpreted as a "low-level sign of heightened arousal or agitation."
"But, I certainly wouldn't call it a full-out aggressive display by this particular male hamadryas baboon," he continued.
If bothered, the baboon likely would have bared his teeth or hurled himself against the glass toward the man. Before the trick, he said he also appears "quite relaxed" while "sitting quietly."
The baboon isn't the only creature to be shocked by such sorcery.
Another video uploaded to YouTube in December showed an orangutan rolling in hysterics when a man made what appears to be a sweet gum seed vanish inside a Styrofoam cup.
