A general note of remembrance for the holiday of green beer and green Chicago River.
The first two are holdovers from last week, when we had other things a-posting and didn’t remark Saint Padraic’s Day on CIDU main feed. A few helpful readers posted St Patrick’s Day jokes to the thread for that day, thank you for renewing the principle of thread drift!
This one was sent in by BillR, looking for what the gag is. It provoked a good discussion behind the scenes of CIDU, where we soon enough agreed on the intended gag but remained divided on whether some terminology was being misapplied!

(For the tag-watchers [or actually, category], yes this post is marked both CIDU and not-a-CIDU. Those just apply to different cartoons, that’s all.)
