's gem "Pointless"
: a first-person narrative from Al's POV as he mother-hens Ed through an unexpected visit to the infirmary. The character voices are dead-on and the joke beautifully constructed (with bonus points for the comic deployment of accurate period detail). Delightful stuff; share and enjoy!
