 After furiously pounding his head on the piano (with Bugs sarcastically asking what that "song" is) and realizing he's not going to have any money left if the temper-losing deductions keep up, Sam gets an idea to kill Bugs and make it look like an accident.He saws a hole in the floor outside the bathroom door and covers the hole with a mat so that when Bugs comes out of the bathroom and walks over it, he will go through and plunge into the river below.When Bugs still will not budge from the bathroom, Sam bursts in and pushes him out, but Bugs traverses across the covered hole and Sam falls through it, cursing in gibberish all the way down.
