Hark! Are those cannons I hear?

Charlie was an aspiring stage actor who was still waiting for his "big break." He rarely got called for an acting gig and was near the point of giving up on his dream.
Finally, one day, his agent called and said "Charlie! I've got good news! I got you a gig! It's a small part, only one line. You play a guard in Napoleon's army. The downside is the show opens today, so you've got to get moving if you want the part. Your line is easy. All you have to say is 'Hark! Are those canons I hear?' Think you can handle that, Charlie?"

Charlie was ecstatic. "Yeah! I can do it! 'Hark, are those cannons I hear?' Easy! When do I gotta be there?!"

"Tonight at 7pm the curtain goes up, Charlie. Don't blow this! It's your big break!"

So Charlie started practicing right away... "Hark! Are those cannons I hear?" he said has he showered. "HARK! Are those cannons I hear?" he said as he shaved. All day long he paced around his apartment; "Hark, are those CANNONS I here?!" "...HARK! Are...those cannons I hear?" All through dinner: "Hark, are those cannons I HEAR?" "HARK! ARE THOSE CANNONS I HEAR?!" Through his afternoon nap, he mumbled to himself: "Hark, are those cannons I hear..."

And, of course, he overslept. His phone rang at 7:45pm. His agent. "Charlie! Where the hell are you? You're on stage in thirty minutes! Get the fuck down there!" Charlie clambered out of bed... "What was my line again? oh yeah; Hark! Are those cannons I hear?" He hailed a cab; "Hark! Are those cannons I hear?" All the way to the theater; "HARK! Are those cannons I hear? Hark; are those CANNONS I HEAR!?"

As he ran through the stage door, the director caught him; "Charlie! You're on in two minutes! Get your costume on! What's your line? Do you remember your fucking line?!"
"Yeah, it's 'HARK! Are those cannons I hear?"
"Great! Get that fucking costume on and get out there!"
As Charlie pulled on his costume he repeated his line over & over; "Hark! Are those cannons I hear? ...HARK! ARE THOSE CANNONS I HEAR?! ...HARK! ARE THOSE CANNONS I HEAR?!"

He made it to his point on stage just in time. From off-stage there was a great loud **BOOM**! and Charlie hit the deck and screamed "WHAT THE FUCK WAS THAT?!"
