This occurs most often with George, either in pursuit of a woman or in a desperate attempt to shed her after a desperate attempt to attract her. George gets a wild look in his eye, concocting some grand scheme that usually involves a catastrophic, traumatic injury. Jerry warns him that it won't work, but George is sure that it will. Elaine just rolls her eyes, and Kramer gives George a slap on the back, telling him to giddy-yup go. Then when it all goes horribly wrong, Kramer does a double take and George vows to swear off women until an hour later when he is desperate for the woman he just tried to dump.
(Sometimes you may insert "money" for "woman" above)
"Kramerica" -- a stroke of writing genius, as was the game show set. Kind of a poke at those folks who have Enterprise bridge sets built in their basements. Maybe Kramer ought to be beamed up by aliens on the last episode. No, wait. "Night Court" did that one.
