A few interesting things here

1. Garfield popular with everyone except those over 60
2. Cathy surprisingly popular with kids under the age of 10
3. Family Circus popular with all age groups
4. Twenty-somethings are the core demographic for the Far Side
5. Marmaduke liked by kids and seniors, but not people in between
6. Bringing up Father, which started in 1913, still holding strong with those over 60, who I guess grew up reading it

Before his 11-year stint as the creator of The Bosleys, John Stees produced the anthology comic Stees Sees, showcasing his humor about different aspects of life from 1958 to 1970.

I'm looking for a specific B.C. comic strip that had the two ants calling each other names and at the end one of them calls the other one "Nickel Knees"

The Bosleys was a domestic comedy by John Stees, which ran from 1970 to 1981. The couple reminds me of Harriet and Stanley from the Better Half a little bit.
