ELI5: Why cant they just pull the metal pin/rod/wire striaght out of the c4 clay in bombs?

Like in movies, they always struggle to desarm the thing. Why can't they just pluck away the clay, or pull the pins out of it? 

Is it just a movie thing?

Also, sorry if I flaired it wrong!

Reasonable bomb makers might add a component to sense the removal if the detonator and trigger it; and trigger the backup they molded into the middle of the block of clay.  It fact, there is no reason to leave detonators sticking out in a real bomb, that's just a thing they do on TV to signal "BOMB".
