Every year, I put a comic in the break room on the day after Thanksgiving because it's a stressful day and we need a laugh. I'm pretty sure this is from 2003.
I had quit doing Spamfish comics years before, but somehow, he fit for this comic. His name has lately changed to "iSquish".
As for the Chinese lettering, I'm pretty sure I made it say, "I'm big". I know the second symbol means "big".
