Need something old, something new, something borrowed, something blue for your wedding? Why not deck your cake with the TARDIS from Doctor Who?
Put your parents' old-school wedding cake topper back in the attic, because your wedding day should reflect your personality and interests. If you and your significant other tend to lean towards the nerdy side, there's no reason you shouldn't geek out at your wedding too.
No one will remember another flowery, white wedding cake, but they definitely won't forget a Lego cake or Mario and Princess Peach topper.
