The "ABCs of BBM": Round 965! (Rules in first post)

[southendmd]

While Jack became discombobulated by the sheep mix-up, Ennis handled it with equanimity.

{def: composure under strain}

[Toast]

Ennis never forgets how important Aguirre could be:

                    JACK
          Fuck Aguirre.

                    ENNIS
               (frustrated, making a point)
          Fuck Aguirre? What if we need a work for him
          again? We gotta stick this out, Jack  [screenplay]

Separating the two herds of sheep involved a little guesswork since some of the paint brands were worn off.

[southendmd]

After the sheep were finally separated, Jack treated Ennis to a harmonic tune on his harmonica.

[Toast]

Indelibly marking sheep with paint brands is such a problem that Wyoming also uses eartags, registered earmarks, tattoos or fire brands to help sheep herders like Jack and Ennis make more positive identification possible.

[Fran]

After the sheep were untangled, Jack, in a better mood, began to play his harmonica and Ennis joshed him about his playing:

"You'll run the sheep off again if you don't quiet down."  [screenplay]

[Meryl]

Jack and Ennis tried their darndest to be accurate in separating the two herds of sheep lest Aguirre find out about the mishap.

[southendmd]

Jack mean-spiritedly yells, "Fuck Aguirre" and flings a sheep almost at the same time.

[Toast]

While they were nudging the herd along, Ennis joshed Jack about his attempts to play a tune on his harmonica. 

[Meryl]

Jack's frustration with the sheep screw-up results in his exasperated outburst of "Fuck Aguirre!"
