Cardboard box... 101 uses??

Question

In MGS4, quote 'A generic cardboard box. It may look pedestrian, but its light, sturdy, and has a hundred and one uses -- how would we get by without them? A good cardboard box is a soldier's best freind -- having one handy can mean the difference between life and death.'

What are these 101 uses?

Answer 2

It's a box - you can put things in it.

There you go. Use #1

As my colonel told me "I'd rather have my 3 ply 14 gauge corrugated 12 fold box by my side than this pesky M16 ! " - and he was right.
