This hilarious Father's Day prank card looks innocent but plays "Dad, Dad, Dad" non-stop 

How the Endless Musical Card Works 

1. Open the card to test the sound; sign it, close the card to stop the sample
2. Insert the card into the envelope; pull the tab from the spine to arm it.
3. Once the recipient opens the card it will start and loop non-stop even if they close the card; it will run until the battery dies; hours later
4. If the recipient tries to break it we hid glitter inside the card

*Plain white envelope included in all cards

Perfect Father's Day Prank Gift

• For those who want something much different from all other Father's Day cards. 
• Your dad likely texts you "what did you send me?!" so it might even start a conversation if you haven't talked in a while. 
• Unlike paper cards that close and they quickly forget about you and the card; this one will continue to remind them you are there.
