Amazing Superpowers of Library Patrons

2008 is the summer of the superhero movie, but we have hundreds of people with their own superpowers walking among us. I'll wager your patrons have other, equally amazing superpowers-- please share!

--Inducing daily paper jams in the PC Res receipt printer. (How do they do that? Identical printers at the circ desk never jam.)

--Can make any book inserted in the book drop land face down and splayed open, for maximum spine/page damage.

--Intuitive mastery of complex mathematical formula needed to determine most thinly staffed/busiest hour in the week to bring in 10 family members to sign up for library cards.

--Ability to indefinitely occupy whichever aisle the last ten books on your cart need to be shelved in.

--Can psychically determine which of the 100 items they have checked out are readily available and cheap-- and return those 99 items safely. 100th item-- limited edition and out-of-print-- dropped in bathtub.
