@Matticus:
I started this a week ago, and got stuck on the last line...finally finished it. It's not as good as I was hoping for, but I don't think I can do any better.
This is the only "proper English" one I could come up with. Using numerals as homonyms and allowing for leet speak opens up a lot of possibilities.Code:CAD BADE DEB ABED DEB EBBED, CAD BEEFED, DEB CEDED DEB DABBED BEADED FACE
The slightly salacious nature reminded me of limericks, but given how hard it was to find enough sensible content for 3 short lines, it seems unlikely I'll come up with 5 longer lines, especially when considering meter and rhyming.
