I love this cartoon because you really have no idea where it's going. The initial gag is funny, but it builds up so nicely. I just love how it changes its main joke. It really is unpredictable. The animation is pretty nice too. I understand the title now!
Not much else to say. It's pretty direct with its humor. I can appreciate that. You'd think the gag would just end when he found out what he wanted a heart. It almost seems like two cartoons in one.
