Tails day of quietly tinkering in his workshop was ended as Amy Rose once more barged into his workshop. He briefly wondered if a 'Sonic isn't here, please stay out' sign would help. Maybe some kind of stun gun turret too...

"Sonic isn't here, Amy," He said reflexively.

"Actually, I'm here to ask you a question, Tails! You don't like your real name much, do you?"

"I'm not really a big fan of it, no. Why?"

"Well, it could be worse. Imagine how dumb your name would have been if we used Metric!" She giggled and left.

Tails decided to build the sign and turret.
