The Ultimate Prank Mother's Day Card! All our prank cards come NOT ACTIVATED so that you have a chance to sign the card and send it off to your mum. This endless Mother's Day card plays a rather unpleasant and potentially PTSD inducing loop of "mum, mummy, mamma, mum, mum!" The nagging loops non-stop (3+hours) , opened or closed, until the battery dies + glitter inside if/when she rips it apart. Add EXTRA spice to your card with our Flying Butterfly Card Prank Specifications: Instructions for use: Step 1 - Open the card and add your personal Mother's Day message. The song will play when opened so you can hear the sound! Step 2 - Close the card and place into the envelope. PULL (do not tear or rip) the safety tab out of the card. Your card is now activated and ready to gift. Step 3 - Gift to your Mum (victim) and get ready to laugh hysterically when she opens and realises the nagging sound will never stop! Step 4 - Let her know the sound will only stop if she breaks it apart and destroys the speaker. Continue rolling on the floor in laughter as she's covered in glitter!
