"Yes you can, Yellow Coward"
The photo about says it all really. This was a mousepad I spotted in a shop, and its the kind of idiosyncratic use of English typical of Japanese products. No doubt the designer/copywriter thought it would be just the right kind of encouraging, uplifting message to give to a friend who was down in the dumps.
I can just imagine cheering someone up with this ...
"Yes you can!"
"Go on, say it!"
(more slapping with mousepad)
"err ... I can?"
"Yes!! That's right! You CAN, you Yellow Coward!!!"
