Cold One

From Homestar Runner Wiki

Cold Ones are a type of beverage that comes in brown bottles. It is hinted to be alcoholic, but this is never said outright.

"A One that isn't Cold is scarcely a One at all."

See property of ones.

Strong Bad can use the diamond-shaped thing on his head to open them, though he has used this power only once. See super powers.

Also comes in Xtra Cold, Not So Cold, Room Temperature, Warm and Cool varieties.
