They usually don't exactly skip. There are several factors that may create the appearance of this.
Tornadoes fluctuate in intensity.
Some tornadoes have smaller, more intense vorticies in side the main circulation. These vorticies can produce very narrow swaths of more intense damage.
Some tornadoes have very narrow damage paths.
The quality of a building's construction can affect how much damage it takes.
Not usually. Some tornadoes have skipping paths, but the touchdowns usually occur along a relatively straight line. Some accounts of tornadoes "skipping" in which a tornado contains multiple vortices inside the main vortex. This can result in a wide swath of moderate damage with smaller areas of severe damage. In other cases, accounts of tornadoes skipping may actually be the result of one thunderstorm spawning several tornadoes.
Not really, no.

Yes!
You can skip them by pressing the Start button.
Tornadoes are not alive so you can't really say whether they survive or not.
Well, you can't skip a grade unless your really extremely smart.
Not really. Although hurricanes and tornadoes have some notable similarities, they are completely different phenomena. It is not uncommon for hurricanes to produce tornadoes, but most tornadoes are not a result of hurricanes.
Sort of. There are firewhirls, vortices of smoke of fire that resemble tornadoes. However, they technically are not tornadoes and have more in common with dust devils.
Not really. Although tornadoes can hit Tuscon, it is unusual and tornadoes stronger than EF1 are rare in Arizona.
Yes. In some cases a tornado will touch down and lift several times before dissipating. This is not to be confused with a tornado family, where a storm produces multiple tornadoes in succsession.
Not really. While tornadoes do occur in New York, strong tornadoes are rare and deaths are even less common.
