Queen Elizabeth had been in her royal loo for quite some time. An attendant cautiously approached the door of the lavatory. She hesitated, then knocked quickly and as quietly as possible.

“Your Majesty…is everything all right?”

There was no reply. The attendant knocked a bit louder.

“Your Majesty?!” 

Still no response. It was nearly time for Afternoon Tea with the Dutchess of York. The Dutchess hated to be kept waiting.
An emergency meeting was ordered, with several of the highest officials of the royal family contacted and brought into the royal bedroom. The Prime Minister was present, and seemed the most worried.

“I…I think someone should go ahead and, um, go into the loo to see if Her Majesty is in trouble.”

The committee put it to a vote and agreed that Beatrice, the Queen’s private secretary, would enter the loo. Beatrice approached the door of the loo and knocked quietly. Still, no response. Beatrice turned the doorknob and slowly pushed the door open. There was no one in the loo.

“There’s no one in the loo!” she announced to the others.

“That’s impossible,” the attendant replied. “I saw her go in there myself, less than 15 minutes ago.”

The Prime Minister pushed everyone aside and approached the lavatory door.  “Excuse me a moment.” he announced to the others, then he stepped inside and closed door.  

Quickly, he pushed back the large armoire that was snugly nestled between the toilet and the bathtub. On the back of the armoire was a small cedar panel. He tapped 3 times in quick succession on the panel. It slid open, revealing a control panel consisting of blinking lights and a multi-colored keypad. He quickly entered a code on the keypad. 

Wooosh!  Immediately inside the bathtub there appeared  a translucent holographic chamber. Inside the chamber stood Her Royal Highness the Queen.  She was flailing her arms and mouthing something he could not hear. The Prime Minister reacted quickly, pressing the flashing panel on the front of the chamber.  The door to the chamber slid open and out stepped the exasperated Queen.

“I am getting too old for this rubbish” the Queen exploded. “Someone needs to fix this bloody time machine!”

The Prime Minister did his best to calm her down. “I understand, your Majesty. You only have a few more trips to make. “ 
He reached into his pocket and pulled out what appeared to be a holographic envelope. He opened it and read the contents of the letter.  

"Congratulations,Queen Elizabeth, on your successful appearance at the 2050 Commonwealth Games.  Before relinquishing your crown, we. the Dracoloids of Farvar, now only require you to make one more trip into your future, to insure that your lineage will remain intact until our Overlords come into power in 2052.  Your next set of instructions will arrive shortly."

The Queen grabbed the letter from the Prime Minister, crumpled it up, and flushed it down the loo. 

“This job sucks!” declared the Queen.
