Jack Link's - Joy Buzzer
Summary: A man shakes bigfoot's handwhile wearing a prank hand buzzer.
Part of the "Messin' With Sasquatch" series.
The couple is walking in the woods when they notice Bigfoot, who is distracted by butterflies. The man puts on a prank hand buzzer and walks up to Bigfoot offering out his hand to shake. Bigfoot, though apprehensive at first, reaches out and shakes the man's hand. When he does the buzzer goes off and the man laughs. Then, Sasquatch becomes angry and rips the man's entire arm off and throws it.
There's also a version where the behemoth picks up the guy by the arm and tosses him.
