Yeah. I was just thinking that too. Then looked again and realized that gay men also got erased (unerased?) as well. Seems a weird mixing of scopes to specify homosexual women but just generalize "men" as though all men like boobs as much as us (mostly)heteros do.
Kari volunteered to work in a coffee shop, disguising her appearance with a wig and makeup and using three different bust sizes: “small” (taped down to achieve a reduction of two cup sizes), “medium” (no alteration), and “large” (DDD size). Grant and Tory watched her through hidden cameras and gave her a tip jar rigged to separate tips given by men from those given by women.
They focused on the tips Kari collected from the first 80 male customers on each shift. During the “small” and “medium” shifts, she collected $72 in tips, while the “large” shift yielded $98, with both men and women tipping almost 40% more. The team classified the myth as confirmed.
Yeah, Mythbusters is fun and interesting, but don't mistake it for a scientific study. IIRC, Adam Savage himself has said they couldn't really apply the level of scientific rigor it would take to actually prove things due to the format of the show.
