Heiji was among Shinichi's best friends, certainly, but sometimes the Osakan was beyond comprehension, even for a detective like Shinichi. He was never more incomprehensible than when he was excited or angry.

"Sure, whatever. I won, so you're buying dinner."
"Fug-ngts!"
Shinichi arched an eyebrow. "'Fudge nuggets'?"
Heiji turned beat-red.
