For me, curls are one of those aggrivating exercises, just because it is such a stereotypical exercise for men to be doing.
If I were to go into the gym on Monday and watch (especially in the afternoon)... I will find this routine, multiple times.
Bench Press, Incline Bench Press, Standing or Preacher Curls with the bar (at worst, in the squat rack), hammer curls. The curls are with the utmost AWEFUL form, where they have far too much weight, and use thier back to get momentum on the weight, then rotate their shoulder(s) under at the top. Most are done at this point. The dedicated ones will toss in some triceps of some sort for balance, then some abs. You can find some decline bench as well.
None of them will show up on Tuesday, about 25% of them on Wednesday to finish up with their backs. Neigh a squat, deadlift
