A man named Jacob Kaufman from San Francisco is also known as "The Muffin Man." It's because he bakes muffins for the homeless, and launched National Muffin Day.
Over the weekend Kaufman had a baking party at Hayes Valley Bakeshop.
Kaufman is rallying others to join the cause, take a picture baking or handing out muffins, and post it on social media with the hashtag "GiveMuffins." For each baker, he will donate $10 to a nonprofit called Project Homeless Connect.
