Visible crew/equipment: While J.J. is in the police station cell with the mean prisoner who had beaten up five guys, J.J. quips, "A hundred prisoners in the jail, and I got to be in a cell with George Foreman." Then, in the next shot, the boom mic dips into view at the top right side of the screen. (00:12:25)
J.J. Becomes a Man: Part 2 - S2-E3
Visible crew/equipment: At the police station, when Florida is begging James to borrow money from the loan shark, she and James stand up; Florida is on the left, James the right. At the top of Florida's head behind her, you can see the microphone dip into view overhead, and it moves quickly out of the frame. Then it's visible again as Florida and James walk toward the loan shark. (00:18:00 - 00:33:00)
Visible crew/equipment: After JJ gives Michael his little black book, Penny spots Boom-Boom's numbers. When Willona walks over and sits on the back of the couch, her mic transmitter wires are hanging out the bottom of her sweater behind her. Then, when JJ doubles over in pain, the bulge of Willona's mic transmitter is visible at her lower back. (00:04:15)

For some reason, I always thought it was the other way around but really no way of knowing. I'm assuming your answer is based on how Florida looks their directions near the end of the episode while saying their names.
They are listed as such on IMDb.com. So it is possible to check. Doug Grant played Sweet Pea and Michael D. Roberts played Neck Bone.
