I did significant research on Google, Firefox, DuckDuckGo, Bing, Youdao, Goo, the darkweb Tor, the public library, the Boy Scouts, the Girl Scouts, Forrest Rangers, Zoo Keepers in China, even the oldest person I know. And conclusively I can say the number of Bears that wear pants is the same number of Bears that wear sweaters. Of course this is limited to the four legged variety 'Bear'.
