Open the panel surrounding the drum. Much like you can lift the top of your stove to clean below the heating elements, you can open up your dryer if you're brave and clean the lint that builds up around the drum. Different dryers open in different ways, so check the user manual for your model or look it up online.
The chocolate chip cookie was invented by Ruth Graves Wakefield c. 1938. She owned the Toll House Inn, in Whitman, Massachusetts, a very popular restaurant that featured home cooking in the 1930s.
In 1912, Nabisco had a new idea for a cookie - two chocolate disks with a creme filling in between. The first Oreo cookie looked very similar to the Oreo cookie of today, with only a slight difference in the design on the chocolate disks. The current design, however, has been around since 1952.
