Kramer invites Toby to see Jerry's act, where she variously cheers, boos, and hisses him, thinking this to be part of the stand-up comedy experience.
He panics when a small grease fire breaks out in the kitchen and pushes down everyone in his path, including Robin's son and mother and an elderly woman with a walker, in his rush to get out.
However, when he spots a prop comic holding a fake gun, he screams, panics and runs away (as he did with the fire), ruining Jerry's act.
[2] The Toby/Elaine rivalry was inspired by the office politics at a show next door to Seinfeld; one of the employees had lost a baby, and some of her co-workers were jealous of the attention their boss gave her because of this tragedy.
[3] Robin was played by Melanie Chartoff, whom Larry David and Michael Richards knew from the time they worked on the short-lived sketch series Fridays.
[2] The sequence where he finds the toe and ices it inside a Cracker Jack box was filmed, but not used, and appears among the deleted scenes in the DVD release.
