"The Explosion waits quietly"

In the film Steel, a Mook tosses a grenade into a room that Shaq and his friend are locked in.... but it does not go off. The two have a short conversation where the friend teaches Shaq how to throw, And they throw it back to the mook where it finally goes off. As the Nostalgia Critic points out, grenades should not take this long to explode and shows a more realistic outcome of the scene.(In Real Life, hand grenades detonate in 5 seconds AT MOST).
