If you want to buy a fun gift for a librarian, check out The Illustrated Librarian Temporary Tattoos.
The description of the product reads, "Librarian stereotypes are as old and outdated as microfiche. Nowadays you're just as likely to see your local librarian driving a Harley as a Honda Accord. This 3-1/2" x 4-1/2" hard-cover book contains twelve non-toxic temporary tattoos ranging in size from 1-1/2" to 3-1/4". Put one in a prominent place to prove once and for all that smart and cool are not mutually exclusive! Also great for bibliophiles and bookworms. All colors follow FDA cosmetic regulations."
What a deal for only $7.95! I wonder if the Library Dean will notice if I put one of these on my forehead before the next staff meeting?
