When a male cake and a female cake fall in love, cupcakes are created via heterogenesis.

Some cupcakes, just by their inherent nature, are cooler than others.

Others we may percieve as being "different" judging on the colour of their cakey base or by the kind of people they choose to associate or perform sexual activies with. However, all cupcakes are one in the same, regardless of taste or appearance.

Except for space cupcakes, which are slightly different, and may or may not be detrimental to your health.

Some cupcakes have a perfectly formed swirl of icing on top. I'm still unsure of how they manage to do this.

This one has a company logo on it.

And these ones, alas, are not for eating, but are awesome nonetheless.
