I’m just going to copy and paste from the auction where I found this thing…
WWF Superstar The Undertaker Sound Bank – This bank stands 8 to 10 inches tall and manufactured by Ringside supplies. You can make the Undertaker say “The Undertaker rest in peace.” by either pressing a button or putting a coin in the slot located on the back of the Undertaker’s head. The figure is in mint condition, the box is in good condition. The bank is opened by twisting a hidden trap door on the bottom of the bank.
They might as well have called this the “ANNOY YOUR PARENTS” bank because that’s what it did.
