Hank asks if the Thatherton Fuel employee Rita Bevacqua is related to former Texas Rangers 3rd baseman Kurt Bevacqua. In real life Kurt Bevacqua played major league baseball from 1971 to 1985, including with the Texas Rangers in 1977 and 1978.
The phrase "Thatherton!" uttered by Hank and other characters in frustration, is an homage to the Seinfeld television series where Jerry would often say "Newman!" to himself as a sort of curse in vain at the character Newman, whom he considered to be his enemy.
