1. Kids in the library: I kind of like that the education majors tutor elementary school-age children in the library. That's one thing I miss about public libraries - the little kids. Today I had to call on all my librarian brainpower to supply kleenex and a pencil sharpener. It's a tough job, but someone has to do it!
2. "'Old school' books": I found some books for students doing a group project - the books were published in the 1920s or so. Upon returning to the table at which the group was working, the particular student I helped exclaimed to his groupmates, "Check out these 'old school' books! Look how old they are!" (Of course, I must admit that when I first looked it up in the catalog I laughed and told the student that the books were from the 1920s).
3. Lazy students: Why discuss back and forth whether or not you can use the CD you want to play during your presentation as a source? You've now spent more time discussing this than it would take you to find more sources. Of course, the students later asked the librarian (me!) and ended up with everything their hearts could desire.. and more. They needed 3 sources, but they got 4 circulating books, 3 reference books, 2 CDs, and a partridge in a pear tree. :)
