Look at this video:

It's not conclusive, but I would say that a baseball feels more rigid than than a golf ball. Yet, you still see the same deformation; though, to a smaller degree, which is expected.

I can't authenticate this without further information, but it doesn't seem unreasonable..

This is ludicrous. Case in point: "Bitch Slap." This movie is horrible and would give any feminist nightmares, yet the entire script is carried almost entirely by a cast of 3 women, with names (albeit stripper ones, but the male names are on par), and talk to each other about something other than men. So this movie passes the test, yet is probably the worst type of representation of women in films. It's basically a porno without the sex.
