Amos Hosne had to take a lomg trip into the desert and his camel was not up to it.

He went to see Abu Bobert, the used camel trader. Abu Bobert sold him a camel garnteed to last 10 days with out water.

On the way back after 9 days the caamel dropped dead. Amos had to walk the rest of the way and barely made it alive.

He accosted Abu Bobert and demanded all his drachmas back. Abu said "did you brick him before you left?" Amos said "what the hell is bricking?" Bobert said "when you take your camel to the watering hole and let him drink his fill, you wait untill he just starts to lift his head up out of the water and you clap two bricks together on his gonads. The camel will go UUUUUUUUUUUNNNNHHHHHHHHHHAAAAAAAAAAAAA! and suck up enough water to last that extra day."
