Can you believe that a major cartoonist would rip off a memer like this?
It could be coincidence, but I think that the timing is fishy because it's about three weeks from the time that a cartoonist submits their stuff before it's published in the paper!
I have no doubt,... cartoonist,.. comedians,.. etc,... search these sites regularly for ideas. There is great humor and wit on this site,... hands down!
