To the Romans, I’m C; When I’m C, waters boil;
On the field of the pigskin, the yards of the soil;
I’m the years that the English claimed they were French royal;
And this riddle among every Thursday dawn’s toil.

Who am I?

I’m a double-decked sandwich with turkey or ham;
I’m the place where you went for the pool where you swam;
I am not thrown in golf; but by jugglers, I am;
And I keep your car safe as a steering wheel jam.

Who am I?

I’m the cereal king; I’m the office of mail;
I’m the etiquette queen; or providing your bail;
When you’re hanging a notice with hammer and nail;
And in smarts, I am often compared to Dan Quayle.

Who am I?

I’m a group of musicians, or outlaws too bold;  
I continued to play as Titanic grew cold;
At the office, I’m rubber; in marriage, I’m gold;
And I’m found on cigars at the time they are sold. 

Who am I?

I’m a movement that birds use to soar through the air;
When your arms trace an arc while your elbows stay square;
I’m the place where you zip up the pants that you wear;
And a helper in fishing the fish find unfair.

Who am I?

I’m a Congressman known for my craving of pork;
I’m a college and high school, both found in New York;
A third single by Dido; another by Björk;
And my gonzo inspired one P.J. O’Rourke.

Who am I?

I’m the Bengals of Bangladesh; cats of Detroit;
I’m the year of Jay Leno, Star Jones, and Jon Voight;
On the Mac, I’m a ten-four; in golf, I’m adroit;
And the flakes that are frosted, I loudly exploit!

Who am I?

I’m six notes on the trumpet that hold high regard;
To ask money for payment; or put on your card;
When a basketball player is rough with his guard;
And in battle, I’m rushing the enemy hard.

Who am I?

I am read for the course, but I’m blue for the test;
Take the music from musicals, I am the rest;
I’m reserving a table or signing a guest;
And to enter a charge that completes the arrest.

Who am I?

I’m the dish, whether soup or the salad you chose;
I am super at football, like sugar or rose;
I’m the way you play ten-pin; in cricket, I’m throws;
And a trivia contest where teams can oppose.

Who am I?
