Yup, they're Ninjabread men cookie cutters! Thanks Fred and Friends! You're cool.
I've wanted to get these for ages now. When I first saw these online I sent a link to my nerdiest big brother, giving a very obvious hint that I would make him cookies if he bought these for me. It didn't happen, perhaps I need to be more blunt next time.
Anyway, I saw them on special somewhere and couldn't resist buying them!
If you like things that are awesome, involve ninjas, giant gorillas and people who ride raptors, you'll love the Dr. McNinja webcomic.
But it's addictive. Don't say I didn't warn you.
