Monochrome jokes

What do me and Monster cans have in common? A barcode.

What's white with black spots? A cotton field from above.

What turns red, blue then white? The last person that I'd strangle.

What's both red, white and sometimes purple?

My arms...

I was kinda right. They used to not let colors in a lot of areas.
