kitty
Lucille in the pilot says she 'dipped into the kitty' referring to the companys funds and later in s2, we see a scene where at an office party an employee says George sr 'has been into the kitty' referring to both the company funds and his affair with kitty.
I'm on my first rewatch (though i havent seen s4+5) and theres many things im catching for the first time and this one is such a small detail but it stood out to me
