Subverted: Only bombs can blow up, despite Explodium abound.
Double Subverted: But enough effort can make walls spontaneously explode anyway.
Parodied: Running From Explosions 2 depicts exclusively explosive weapons, stars Action Bomb as a protagonist, ends with a massivenuclear strike, and is advertised as "the best movie about explosions you'll ever see".
Reconstructed: Characters firmly know just how dangerous all those explosions are - and so ones take cover when appropriate, while others are never seen without flak jackets and helmets.
Played For Laughs: After none of Bob's homemade grenades turn out to not do any damage at all to their targets, frustrated, he throws the last one away over his shoulder, causing a parked civilian car to go up in a fiery ball of fire.
