In my state (somewere in the Mexican rainforest) there is a saying: En esta vida matraca, caga el buey y caga la vaca y hasta la chica mas linda hecha su bola de caca... but i think you don't speak spanish so, this is an aproximated traduction: In this twisted life poops the cow and poops the cattle and even the prettier girl... go and takes an hour long dump. I think this little piece of mexican popular wisdom fits quite well to your comic page.
Of course it's a acceptable topic. If that girl was any good, she would politely comment on either what news he had read about or discuss her own bowel movements. You would think a man of his stature would use a more refined word than 'poop' though.
Perhaps talking about constipation prior to going to the store will encourage him to buy high-fiber foods.
uh.... for some strange reason, i wonder about you sometimes.
i was just chatting with my friends and the conversation ended up about you and we had an entire length hour long conversation about you. what i forgot to mention was the question "Does e1n really reads wikipedia and cell phones when he takes a dump like his characters?"
I wonder about the strangest stuff sometimes...
Oh, and I've never had a girlfriend, maybe it's cause of the lack of poop in my conversations. We should try that next time.
