My Mouse is Andy Kaufman
In light of this, I can only conclude that Algernon the Office Mouse is likely pulling an Andy Kaufman-esque stunt.

Algernon has disappeared, and has been missing for several days now. He has eaten none of the poison and has not been fatally injured in any of the traps set for him.

Therefore, I can only conclude that he has chosen to fake his death in a massive stunt to fool me into thinking he is gone or dead, and he will someday return when I least expect it, in a way that will shock and awe us all.

It only makes sense.

He's that smart and sneaky and mean.
