A bodybuilder was busy training on the beach when a couple of young girls came running past. He saw this and started posing for them. He showed them his biceps and said, "Ten pounds of dynamite!" And, the girls almost fainted.

Next he showed them his bulging chest and said, "Twenty pounds of dynamite!" And, the girls started screaming.

At this stage the bodybuilder was so full of it, that he desired to show them his legs. He bulged his left leg and suddenly his pants fell down.

One of the girls shouted, "Let's run for it. Look how short his fuse is!"
