There are some good reasons to play with TNT in minecraft griefing or for fun but then some people think is TNT as fun to play with in real life? It is sometimes but when u do happen to play with it having no knowledge about explosives u might get a nasty surprise. TNT is actually a deadly thing that if u get to close to u can die! Incase u didn't know. Lots of people have lost there legs arms and minds with this stuff. So moral of this story. Don't do drugs.
