The moon shaped cutout in the door has meant "outhouse" for ages. I guess now you can't show an outhouse in a comic strip?
If there were a way to show it, Hart could do a follow-up: show the T.P. inside the outhouse -- CAIR press releases.
( Btw, when I see a cartoon depicting three crescent moons, I don't think of Islam anyway. I think of "Stargate." So there. )
Only the painfully ignorant don't know about moons on outhouses. Talk about people who do more damage to their reputations by opening their mouths than to the target they attack.
If there were a way to show it, Hart could do a follow-up: show the T.P. inside the outhouse -- CAIR press releases. My version:
The same panels as the original strip but change the dialogue in the final panel...
"Finally I found a use for the Washington Post."
