You will enjoy messing with verb conjugation. Maybe

 I don't know about you but as a native English speaker I don't pay that much attention to conjugating verbs. Maybe I should now that I blog.  

Kenneth Beare does a great job explaining and supporting such things as verb conjugation on his website, http://esl.about.com/b/2012/05/16/verb-conjugation.htm?nl=1 This is just one of the many lessons that are great support to ESL and mainstream classroom teachers. 

I have copied a very helpful chart from this lesson on verbs just to give you an example of what you will find when you explore his work.
