Life Simplified? Heinz Dip & Squeeze Packets

I'll admit it.  I get frustrated trying to open those tiny little packages of ketchup.  Usually end up trying to tear it open with my teeth, resulting in a squirt of ketchup in my mouth, or down the front of my new white, button-down-the-front shirt.  Life has been simplified by Heinz, with their new Dip and Squeeze packets.  Why didn't they come up with this sooner?
