A Slight Touch of Venom Checkmate : Season 1 Episode 35

Status-seeking retired contractor Ernie Venable gets Dr. Hyatt's seal of approval for a new security system, but that doesn't stop someone from throwing a poisonous snake on his property in an effort to scare him, or kill him. The Checkmate team must contend with Ernie's coarse manners while they try to keep from getting pneumonia from staying in his frigid home to find who's responsible and protect him from the snake.
