    Kačeři mají penis do vývrtky
    Why are duck penises corkscrew-shaped and how do they mate? | BBC Science Focus Magazine
    https://www.sciencefocus.com/nature/duck-penis-corkscrew/

    How the battle of the sexes left the duck with an awkwardly long, corkscrew-shaped penis
    Ducks' bizarre genitalia is a result of a sexual arms race. Forced mating is common among ducks, so while males' long, flexible penises increase their chances of successfully fertilising a female, the females' anticlockwise vaginas give them a level of control.
    "Those complex structures prevent full eversion of the penis of unwanted males, so their sperm ends up closer to the cloacal entrance where the females can get rid of it more easily." That is, Brennan's research found that female ducks can prevent fertilisation from unwanted males.

    However, if the female wants to mate with a certain male, she can relax her cloacal muscles to allow easier access.

    No Pants Subway Ride
    You’re probably wondering now, “what am I looking at?” Well, what you’re seeing is a photo from the No Pants Subway Ride of New York, an annual, much-anticipated social event, where people ride the subway in their underwear. Why? Because it’s funny, according to the person who started this annual event. The first No Pants Subway Ride started in 2002 by Improv Everywhere’s Charlie Todd.
    Since then, the No Pants Subway Ride has gained tremendous popularity, and even breached the boundaries of New York, with over 25 countries involved in this madness. While the first event in 2002 included around 150 members, now hundreds of people participate in what has gone to become one of the largest national pranks. Aside from not wearing pants, the people who participate in this event wear anything they would regularly wear, except for pants, and are perfectly normal people.
