Ken loved fruit-flavored gum, but always ended up swallowing it.
One day, Chikusa cast a sidelong glance at his happily masticating companion and asked, "Don't you feel embarrassed to still be swallowing your gum at this age?"
"Shut up!" Ken snapped in reply.
"You know..." Chikusa pushed up his glasses and a malicious glint of light reflected off of them. "If you swallow too much gum, it'll block up your intestines. And then you'll die. From constipation."
Ken's jaws stopped moving in mid-chew as he paused to consider this. He decided to spit his gum out.
The next minute passed by in silence until Chikusa spoke again. "I can't believe you fell for it. Even a five-year-old could see through that. You really are an idiot."
"YOU FOUR-EYED KAPPA! I'LL KILL YOU! I'LL KILL YOU!!"
