The ultimate prank Mother's Day card All of our prank cards are deactivated, so here's your chance to sign the card and mail it to your mom. This endless Mother's Day card plays out a rather unpleasant and potentially PTSD-inducing loop of "Mom, Mom, Mom, Mom, Mom " Nags on a non-stop cycle (3+ hours), on or off, until the battery dies + if/when she rips the battery off, the inside will sparkle. Add extra fun to your cards with our Flying Butterfly Card Prank Instructions for use: Step 1 - Open the card and add your personal Mother's Day message. The song will play when turned on so you can hear the sound Step 2 - Close the card and place it in the envelope. Pull the security tab out of the card (do not tear or tear it). Your card is now activated and ready to gift. STEP 3 - A gift for Mom (the victim), get ready to laugh hysterically when she opens it up and realizes that the nagging will never stop Step 4 - Let her know that the sound will only stop if she takes apart the speaker and destroys it. Keep rolling on the floor laughing as she's covered in glitter Happy Mothers' Day
