Look no further than the stars to figure these two out. John and Ken feel very strongly about Astrology.  I got this information from astology-online.com.

Ken is a Cancer. In other words, he is:

Emotional, loving, intuitive, imaginative, shrewd, cautious, protective and sympathetic. He is also moody, touchy and overemotional.

John is a Gemini. In other words:

Adaptable, communicative, witty, intellectual, eloquent
youthful and lively. He is also nervous, tense, superficial, cunning and inquisitive.

Hmmm...Bologna or no. I wonder what sign Charlie Potatoes is.
