Sometimes, it's not the difficult questions that are the most engaging - but then again, I can be entertained by very little (remember, I'm the kind of guy that is content reading the phone book).
A patron came to the desk and asked if we had any typing tutorial software she could check out. I knew we had books on learning to type, but no software, so I just did a quick search for "typing tutorial" online and the first result is exactly what the patron wanted.
She was happy, and I set her up on a computer to work on it. But then of course I was curious, and started playing with the website myself - and it turns out it is a very fun and addicting program. It gives a live words-per-minute speed indicator, so my game was to get that up as high as possible (also remember, I only use three fingers when I type).
This is also another example of "everything is on the internet, but it took asking a librarian to find it" - but then, I wouldn't expect someone learning to type to be good and online searching. And in this case, I was happy she asked, because not only could I show her how to do an internet search, but now I also have a fun new game that might actually improve my own typing.
