Irony is:
-Taking perfect aim at someone, and pulling the trigger - and having it backfire
-Mugging for exams a whole week - only to find you mugged for the wrong topic
-Putting a lot of effort into making a soup - and tripping over while carrying it, dropping the bowl
-Making a bomb - and having it explode prematurely
-Working hard on a blog post - and having it ignored totally
