To anyone complaining about Sagan stepping on the packages and whatnot... the package is thrown into trucks, they get bumped to hell, packages weighing more than Sagan's weight (which is what, 20-30 Kg?) are stacked on top of that package... if Sagan would mess such a large package, there's really something wrong with the packaging.
And kid near knife, 1m above the floor... really ?! What's the worst that can happen, getting a cut? He'll learn knives are sharp and won't do it second time.
Fall off the desk? At worst case he'll break a hand or a leg, you don't falling from a meter on packages... you learn to live in real world.
Sagan probably couldn't even move from that spot as the camera tripod and Dave were in front of him, and he had packages around the sides.
Jeesh, such people...
Like i said, the only thing I slightly cringed at was Sagan putting the screwdriver in the cooler... now I know there's plastic there and the card won't get damaged but it still felt a bit bad. You don't care that much when it's a gift but when you pay hundreds of dollars you're more attached to stuff.
