Some thank-you cards are sweet. This one is… relentless. Say thanks to Mom in a way only a true Joker would—with a never-ending loop of “Mom, Mom, Mom” that plays for hours. The Joker Greeting Endless Thank You Mom Card is part heartfelt gesture, part hilarious chaos. Once opened, the sound kicks in and doesn't stop until the battery dies or the card meets its glittery doom. And if Mom tries to end the madness? Boom—chunky glitter surprise. Whether you're celebrating Mother's Day or just want to give a “thank you” she'll remember forever, this card delivers laughter, glitter, and a little dose of revenge for all those sleepless nights you gave her as a kid.
