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 (which Coach Z enjoys), Room Temperature, Warm and Cool varieties.
