Dynamite

GRAB it, LIGHT it, and THROW it at someone. But be careful -- you may take some damage from the explosion too!

DEFUSE to destroy lit or unlit DYNAMITE.
IMPORTANT SAFETY TIP--dynamite fuse length is unpredictable.

There's nothing that'll send you to cowpoke heaven like holding exploding dynamite.

THROW : Don't DROP that empty handgun--THROW it at someone (especially if you are well-rested). 

THROW or DEFUSE lit DYNAMITE.
