Can't begin to count the times I've been asked a question, turned around to my keyboard and did a Google search for the answer. Maybe it's my reputation as the world's best, highly paid, administrative assistant.
The web site "lmgtfy.com" can add some levity to the process. Just let the person know that you will email the answer to them, then use the web site to create a link that will do the needed Google search. Email that link and when they click on it they'll get the answer .... and just maybe, the real point you're making.
