Most humans have but two hands to carry pizza. That is not enough.
Stupididiotic considered this dilemma and innovated a solution: the Portable Pizza Pouch.

For $8.00, customers get a triangular plastic pouch with a zip-locked top. The pouch is fitted with detachable necklace for hands-free wearing, meaning pizza lovers can walk around all morning with lunch hanging around their necks.
You'll look something like this.

Potential downsides include the pouch's smaller-than-average-New-York-slice size and lack of storage for various dipping sauces. You can never truly have it all.
