What is everyone using for a cup holder in their classic?

When I'm drinking, I'm in my den, door closed and relaxing in my underwear. I said relaxing.
When I'm in my Classic, I'm driving
In my Classic, I don't drink and drive.
Not even speakers in it.
And no rear seat.
Jus me, the 367, the clutch, and the Hurst, partying dry, no cupholders allowed.
