T-Rex: Sherlock Holmes, who was so good at detection that his name became synonymous with his profession, thereby ruining it for everyone else, frowned.

T-Rex: He'd realized what I'd just told you: his name was ruined for everyone else!

T-Rex: "But," he said, "if I CHANGE my name, I can see PRECISELY how famous I am. Since 'Sherlock' was never an extremely popular name, it easy for me to claim it. But what if I were Gary Holmes? Could I claim 'Gary' as much as I've claimed 'Sherlock'?"
Dromiceiomimus: There was only one way for Gary to find out!!

Utahraptor: And soon Watson did the same thing?
T-Rex: NO!

T-Rex: Watson is his LAST name: his first name is "John" which was ALREADY popular, and probably why he never ruined it for everyone else. That's why John changed HIS first name to something unusual too, eventually landing on "Hairy Cinnamon".
Utahraptor: Ah.

T-Rex: Hairy Cinnamon would spend the rest of his life saying "No, not Harry: HAIRY, like too much hair" while Gary spent the rest of HIS life saying "No, it's a GARY hat, not a Sherlock Holmes hat. I'm Gary now."
T-Rex: To answer your question: yes, this IS canon!!
