A lot of people in that thread have never seen Looney Tunes. If they did, they would have learned 3 vital facts about physics:
A finger in the barrel of a gun will stop a bullet and cause the gun to explode.
Gravity cannot effect you until you acknowledge that you are not on solid ground.
Being crushed by a heavy object falling from a great height (think and anvil or piano) will cause to to collapse like an accordion until you are re-inflated.
These are basic scientific facts everyone should know in the modern age.
Incredibly, they actually drew their cartoons based on observations in nature. The duck season/rabbit season bit commonly seen in the Bugs and Daffy cartoons, while exaggerated was based on true events.
Why are both of these so veiny? Also, why does the word veiny and both of these pictures make me think of dicks? Am I the inevitable perverted product of an overly sexualized society or are these drawings intentionally evoking phallic symbolism? WHAT DOES IT ALL MEAN?
What's hilarious about this is that obstructed barrels actually can explode into ribbons just like the cartoons. A finger might not do it though, and not sure how many volunteers you'd get for a scientific test.
