Phone-bomb thug

This thug was a chosen man for The Joker's cell phone bomb experiment.

History
The fat man various times begged the officers outside to help him, childishly complaining that his insides hurt and babbling that "the boss" would replace "the voices" with bright lights like Christmas. Laughing hysterically in agony, he collapsed. A paramedic and two officers entered the cell and found an ugly scar on the man's belly.

As they studied the scar, a light shone through the man's skin along with a beeping tune. As the officer asked in bewilderment, "Is that a ... phone??", the phone bomb activated, blowing them, and the thug, up at once.
