How to show related post within content

Hello

Is there a way to show related post within post content.

There are plenty of plugins/hacks available for showing related post at the end of post content but I do not find any that can help you in showing related post within the content at random places.

For example check this link to see how they display related post within the content

So I need a head start on this.
