Those Mother's Day eCards and Mother's Day greetings going around the net today are lame! Enjoy our exciting and hilarious JibJab Sendables Mother's Day greetings instead! In this funny video, we've taken biology to a new level by allowing you to wish mom a Happy Mother's Day...with sperm! Remember, without sperm, she wouldn't be a mom, and without JibJab Sendables Greetings, you'd have to settle for another crappy Mother's Day eCard!
