If you're looking to make your friends and family laugh, you probably want to send a funny party eCard that guarantees your recipient will crack up until they wet their pants with childish glee. JibJab Sendables eCards specialize in just that! That's because each funny eCard we cook up is hand injected with Funny Serum, a patented chemical compound we concoct in our secret JibJab Labs (i.e. the men's room). This super secret formula has made JibJab Sendables eCards more effective than laughing gas. That's why 4 out of 5 dentists agree: our stuff is hilarious!
