"Why are we here Holmes?" Watson grumbled as they walked around a junk shop.
"I'm looking for something." Holmes said as he picked up a random item, shook his head, and put it back.
"I can see that Holmes, but why are we looking here?" Watson asked giving a disapproving eye to the sketchy racks and items on display.
Holmes rolled his eyes and walked over to a hat rack. "Maybe I like to shop here." He said and started to try on hats.
Watson shook his head in disbelief and walked around to the other side of the aisle. As he was looking, he spotted what looked like a bug. Leaning in to get a good look, he saw it was made of rubber. He picked it up, glanced at Holmes and smiled. Sneaking up behind Holmes, he put the bug on his shoulder and pretended to walk past him.
"Watson, what do you think of this one?" Holmes asked as Watson "walked by". He was wearing a fedora.
"Holmes, you know that there could be lice in those hats." Watson said with a look of (genuine) disgust.
"What? I've never heard of that." Holmes said as his face went pale. "You mean that evil blood sucking creatures could be in these hats?"
"Yep, but it's too late. Look there on your shoulder, they're already on you!" Watson said with fake horror.
Holmes gave a yelp of fright and swatted the fake bug off of him and quickly backed away from it. But a second later he saw it was a fake and turned on Watson.
"That was a terrible trick to play on me!" He cried angrily as he threw the fake bug at him.
"You set yourself up for it mate!" Watson said good humoredly as he dodged the bug.
