LMGTFY (Let Me Google That For You) is a website that creates a demonstration of how to conduct a user-specified Google search.
The site was designed as a service to tech-savvy people who are frequently asked for help doing research. The purpose is to gently, if somewhat sarcastically, point out that the person who asked for help could easily search for the information themselves.
Here's how it works: On the LMGTFY website, type or copy the question into the search box. A link is generated to a demonstration of a Google search for that information, which can then be shared with the person who asked the question.

LMGTFY is one example of a single-serving site: a one-page, one-purpose website with a dedicated domain name. The site was created in 2008 by Jim Garvin and Ryan Geary, who have since created spin-off sites including Let Me Snopes That For You and Let Me Wikipedia That For You.
