Early in the the show Gary read a text message Sal sent him yesterday: "Sick as a dog. Think it's the flu. Left you office voicemail [cough]." Howard speculated that Sal has been out sick even more than Artie, and Gary agreed, as Sal averaged at least one late-day per month.
Gary said Sal frequently blames his tardiness on LIRR delays, so Howard demanded that someone now check with the LIRR reports to see if Sal's trains really have trouble. Howard joked that (given her recent shoveling out of Sal's car so he could go to work) Sal's wife, Christine, must be in their basement frantically trying to discover a cure for whatever Sal is suffering from.
