Chris (Number Three)'s nose is seven inches long.
Number Five's "diving helmet" used to be a cheap plastic Sinclair (gas station) racing helmet. And yes, those are real 6-inch nails sticking out of it, they are not rubber. They appear to bend because the only thing holding them on is tape. So, they flop around when he headbangs.
All of the dreads on Corey (Number Eight)'s mask are made out of his real hair. There is twine wrapped around them. He cut them off because he changes his hair a lot and got sick of having to pull them through the holes in his mask before every show.
Joey cuts the arms and legs off of his coveralls. Makes it a tad easier to beat on things.
James (Number Four)'s first mask was "inherited" from the previous guitarist named Josh. He wore it until a mask more suited to his personality (the "jester's" mask) was created.
The barcodes on Slipknot's jumpsuits and on your t-shirts aren't entirely decorative, as we've pretty much stated before. The barcode's number has special meaning: It's the barcode from Mate. Feed. Kill. Repeat. (turn your cd over and look on the back for those of you that have one). The barcode number is also the title of the first track on the self-titled Slipknot album.
The colours of Slipknot's current jumpsuits-- Blue, Red, Black, Grey and Green. The black, grey and green ones all look almost like they are the same colour. They have another set of blue ones with silver embroidery on it.
