In Ulrika's bitter challenge, Ulrika drinks a pint of bitter which turns out to be fake and spits out it. Incidentally, the same thing once happened to Michael J. Fox on the set of Back of the Future (1985). Michael J. Fox, in character as Marty McFly, drinks alcohol, but what Michael J. Fox didn't know was that the alcohol in the prop bottle was not real alcohol and Michael J. Fox spat it out causing cast and crew to crack up laughing.
