What is the brand in a beer TV ad where two guys grab same last bottle of and then refusing to release it do everything together still holding that bottle?

The ad you're describing is likely the one with the two guys who grab the last bottle of Budweiser in the cooler, then refuse to let go, even as they end up doing all sorts of things together (like playing basketball, going fishing, etc.) still holding the bottle.

It's a humorous ad highlighting the shared enjoyment of Budweiser among friends.
