If you lived on Mercury, you could have a birthday every 88 days! That's more than four times the presents, four times the parties and most importantly, four times the cake! Quadruple the birthday sounds really great, as long as you don't mind Mercury's lack of good ice cream shops and a breathable atmosphere!If you prefer the creature comforts of a planet with, say, life, we humbly suggest this fine Birthday Cake! It's always fresh and ready to cuddle every day of the year! Get all the benefits of a shorter heliocentric orbit without leaving your home planet!
