Pyjamas

Sheldon's pyjamas

Sheldon wears checked pyjamas. Just as with his eating habits and daily activities, he follows a strict schedule and has different pyjamas for every night of the week. He rather sleeps without part of them than wearing pyjamas of the "wrong day".

Sheldon to Penny: I cannot wear different pyjamas. These are my Monday pyjamas. (0203)
