Creepy Chaperones? Derick Wanted Ben To 'Rein In' Sex Thoughts Before He Married Jessa -- While Jim Bob Gives Them Kissing Lesson Before Wedding

"We know what they're thinking because we were just there. We're not just any other chaperone, we have a unique perspective, so whenever Ben gives her that look, I know that look because I used to give Jill that look.

Dillard said he recalled telling himself, "I need to rein it in right now," when he got hot and bothered as such.

"So if I see Ben with that look -- I might just have to tackle him," Dillard joked.

Jim Bob told them, "Both of you like the physical relationship, but the guy, that'll kind of be the main focus. For a woman, communicating is the most important thing, taking time each day to communicate, that will mean the world to her."

Seewald told his soon-to-be father-in-law he that regularly gave Jessa opportunities to discuss issues.

"I'm not one to yell or lose it … but sometimes I tend to be more of the silent treatment thing and so I really got to watch that," he said. "We've had a few little disagreements, but it's been good working through those and trying to get it worked out as soon as possible."

Jessa thought it was important to agree to disagree.

Jim Bob predicted, "You're going to be a dynamic duo."

Then, the family patriarch demonstrated with wife Michelle something the twenty-something pair hadn't done yet: kissing.

"Let me show y'all the best way to kiss here," Jim Bob said.

"If you kiss straight on, your noses hit together, see," he said, bumping noses with his wife as Jessa and Seewald laughed.

"She turns one way, I turn another," Jim Bob said while kissing Michelle.

Then Seewald told the TLC cameras, "We're saving our first kiss for our wedding day: We think that it could lead to some stuff that we're really trying to avoid before our wedding and so, we think it's wise to hold off until our wedding day."

Also on the episode, Jeremiah acted as the couple's chaperone as they took out an Arkansas marriage license.

"I'm here so they don't break their rules," Jeremiah said.

Two days before the wedding, Jessa and Seewald went to pick up their wedding rings, but Ben kept Jessa's a secret.

When the jeweler gave Seewald Jessa's engagement ring back (he had sized it to fit the wedding ring in the band), Ben got on his knees and proposed to her again just for fun.

He told the cameras he was sure Jessa would love the ring but mused, "If she doesn't, I don't know -- I guess I'll go get a different one."

Also, viewers saw Jessa get her final wedding dress fitting.

The train was too long on the modest blush-colored gown, so she had it altered with a bustle in the back.

Michelle said she wore grandma Duggar's dress when she married Jim Bob, but it was a tight squeeze.
