Frank Rules and the Dead Rising
When you work for a company that actually employs a guy named Tom, all of the common phrases that employ the name 'Tom' for a generic male are no longer work appropriate.
We can't use the phrase "Peeping Tom". There is no Tomfoolery. There is no noting that a person is acting like an old tomcat, or for that matter, Uncle Tom. One is not a Doubting Thomas. One's Thumb is not named Tom. And there is absolutely never any beating of the tom-toms.
Also, some non-homeless people on the bus here in San Francisco smell so awful that I am convinced they are the undead. I have my stockpile of wushu weapons; now is the time to start eying potential holdouts.
