Reminds me of a story. I was in Tokyo (visiting) with a couple friends who were working there, and we were out trying to kill the local beer supply. We all stagger into the john before boarding a train to go home, and there's this Japanese guy in there, so we split up around him, unzip, and one of my buddies looks down and just out of the blue (maybe presuming the dude doesn't know English) remarks, "Hey man, nice dick!"
"Thank you!" he replied, finished up, and casually walked out. We all nearly died laughing.
