Things which go better with heat

The construction worker was taking apart a piling hammer that had some very large bolts holding it together. One of the nuts had corroded onto the bolt, so to free it the worker started heating the nut with an oxy-acetylene torch. The apprentice asked why, so the worker patiently explained that if he heated the nut, it would grow larger and ease its grip on the bolt.

"So things get larger when they get hot, do they?" the apprentice asked.

"Yes," explained the experienced worker. "That is why days are longer in summer and shorter in winter."

After a long pause, the apprentice's face cleared. "You know, I always wondered about that."
