"The Mexican Staring Frog of Southern Sri Lanka" is the sixth episode of Season Two, and the 19th overall episode of South Park. It originally aired on June 10, 1998.
The deadly "Mexican Staring Frog" is sighted in South Park and the town's fearless hunters, Ned and Jimbo, are on the case. Their heroic efforts drive up the ratings for their new hunting show on the cable access channel and threaten to edge out an old favorite, Jesus and Pals.
In this episode, the boys are assigned to interview Vietnam War veterans. They decide to interview Stan's Uncle Jimbo and his friend Ned. The two tell a story of American camps having amusement park rides and claim that they single-handedly defeated the entire Viet Cong army. Their report gets them an "F-" because Jimbo and Ned completely made up their story (this is what Mr. Garrison tells them, anyway). The boys are furious about this and plot revenge against Jimbo and Ned. They make bogus videos of the legendary "Mexican Staring Frog of Southern Sri Lanka", which they send to Jimbo and Ned. The two then reveal it on their show, Huntin' and Killin.
The show becomes successful, which leads to a decline in ratings of their competitors, the talk show Jesus and Pals, starring Jesus. The show begins to alter because of the actions of one of the show's producers, despite Jesus' cynicism of the idea. Meanwhile, Jimbo and Ned go searching for the Staring Frog which, according to legend, can kill with a glance; Ned sees the fake frog the boys set up and becomes comatose from pure fear, and when in the hospital, the boys confess their misdeed. This leads to Jimbo, Ned (though still comatose), and the boys all being shown on Jesus and Pals, arranged by the show's producer.
Without Jesus' knowledge, the producer arranges for them to lie on the air to improve ratings, having Jimbo claim that Stan is a drug-addicted Satan-worshiper, and having Stan claim that Jimbo molested him, etc. When chaos breaks out on the show, Jesus screams "Shut the fuck up!" at everybody and discovers the truth about everything; he patches everything up with Jimbo, Ned and the boys, and as punishment to his producer, sends her to Hell. There, she meets Satan and Saddam Hussein, foreshadowing events that will unfold in South Park: Bigger, Longer & Uncut and later in the two-parter episodes, "Do the Handicapped Go to Hell?" and "Probably".
