Zig Zagged: The game features different classes of spikes featured, ranging from harmless to lethal. Only, the player cannot tell by looking what kind of spikes are on the screen, so it is decidedly random.
Averted: The game doesn't have spikes.
Enforced: The writer was accidentally impaled as a child and harbors a pathological fear of sharp objects.
Lampshaded: "Just be sure to avoid those big, pointy things down there..."
Invoked: The Big Bad is getting reports that the security at his fortress is too easy to bypass, so he places a special order for a spike-based defense system.
Exploited: A way of quickly offing the Demonic Spiders in the game is to lure them into spike pits which kills them instantly.
Defied: The Big Bad decides that spikes are too easy for his nemesis to bypass, so he constructs a complicated laser-based security system instead.
Discussed: "Let me guess, touch the spikes and I die?"
Conversed: "Why do dungeons always have pits with spikes in them?"
The Big Bad constructs spikes inside his fortress for protection, but the maintenance cost of constantly cleaning and sharpening those spikes causes him to go bankrupt and the bank to foreclose.
The spikes will turn out to be too blunt to cause any serious harm.
Reconstructed: The Big Bad purchases specially constructed spikes for his fortress that never go dull and that are made especially slick to prevent stains.
Played For Laughs: Bob makes a suicide in humorous way by jumping into spikes.
Played For Drama: A dead body of a protagonist's friend can be seen impaled by those spikes.
