There should be a sign underneath this one that reads, "The above sign is the most depressing sign this sign-maker has ever had to make. Sincerely, your local public restroom wall-sign maker." And above the 500+ Lbs. capacity toilet it should read, "The manufacturer of this toilet can't believe he had to make this thing. If you're using this toilet, come on man, they make Diet Sprite too. Sincerely, Jeff of Jeff's Huge Effing Toilets, Inc."
