Here is the explanation for each thing for those who might not know:
1) Gratuitous executions
This one is quite self-explanatory
2) The only state where a Mofo, a tough Grandma, and an eccentric singer/novelist can run against each other for governor
Mofo: Gov. Rick Perry was in an interview with a news reporter regarding education reform. Unaware that the camera was still rolling, Perry told the cameraman "Adios, Mofo"
Tough Grandma: Another gubernatorial candidate, Carole Keeton Strayhorn, bills herself as "One Tough Grandma"
Eccentric singer/novelist: Kinky Friedman, another gubernatorial candidate, is a singer/novelist who supports gay marriage because "they have every right to be miserable as we do"
3) 2-day-long hurricane evacuations where, if you cross your fingers, a fuel truck will stop along the road
This refers to the mass evacuation in September 2005 from Hurricane Rita, which was poised to make a direct hit on the Houston area. It took my family 19 hours to get 100 miles inland, and there were widespread gasoline shortages. The most significant incident during the evacuation was when a bus exploded just south of Dallas, killing 23 retirement home residents. Rita eventually made landfall at Sabine Pass, on the Texas-Louisiana state line
4) The ability to morph into five states
There is a relatively unknown law that states that Texas can split into as many as five states. That has never happened as of this date
5) Thousands of farm-to-market roads that don't go to farms or markets
Farm-to-Market roads are roads (usually 2-lane) that are mainly found in rural areas, usually east of Interstate 35. These are called Ranch-to-Market roads west of Interstate 35, and Urban Roads in the big cities. But the urban roads are billed as farm-to-market roads simply to save costs for replacing the signs. The most significant farm-to-market road (in this case, urban road) is FM 1960, which goes through the northern suburbs of Houston.
6) The state bird is the construction crane
Especially in Houston
7) Massive domed stadiums that stay vacant for 10 years
The last time the Astrodome was used for its original purpose was in 1999, which was the Astros' final season before moving to Minute Maid Park. The dome was used as a shelter for the Katrina evacuees, and there are plans to transform it into a resort complex, a la the Gaylord (formerly Opryland) resort in Nashville.
Towns with 100,000 people where the topic of the day is still the tornado of '79
Specifically, Wichita Falls, which was hit by a major tornado in, yep, 1979 (which happens to be the year I was born).
9) Term paper plagiarists
In the 1990s, there was a major term paper plagiarism scandal at Texas Tech. This was referenced on the Simpsons episode "Trash of the Titans"
10) The state tree is the oil well
Let's just call Midland-Odessa the Enchanted Forest
11) Sharing a post office with another state
Texarkana, Texas and Texarkana, Arkansas share a post office and a federal building.
12) The Dixie Chicks--NOT!
They were ashamed that Bush was from Texas, not knowing that Bush is really from Connecticut.
