|First appearance||"Children of the Gods"|
- "Daniel, for crying out loud, you've had one beer. You're a cheaper date than my wife was."
- —Jack O'Neill to Daniel Jackson (SG1: "Children of the Gods")
The effects of alcohol contained in a beer can be more sensitive depending of the person who drinks. For example, Daniel Jackson is very sensitive and just one beer can change his behaviour (SG1: "Children of the Gods").
After their return from Abydos, Jack O'Neill brings Daniel Jackson in his home in the hope to change his mind. There, if brings a second cold beer to Jackson and the two resume their conversation. Soon after, Jackson, having just taken a mouthful of beer, states that this thing "is going straight to [his] head". O'Neill says that Jackson has had only one beer and that he is "a cheaper date than [his] wife was".
- In "Children of the Gods", when Daniel Jackson and Jack O'Neill are in O'Neill's house, Jackson had already drunk one beer as the first emptied bottle is on the chimney.
