Lace may be a little crazy, but it's a new woman who has become enemy number one.

Last night's episode of The Bachelor made us think way too much. I know it wasn't my glass of wine that was making my head spin. Ben started off with a group date that involved taking the girls back to school. Apparently that is where his glory days have been and always will remain. He made them compete in various challenges, eliminating teams of two with each subject. In the end, the winning pair had to race each other for the chance to be crowned Homecoming Queen.

Mandi received the crown.

However, she didn't receive the rose. It was Joelle, or JoJo, who received the group date rose... Along with some major passionate kissing. Ben was feeling her for sure.

Caila received the one-on-one date and the opportunity to hang out with Ice Cube and Kevin Hart, who made a special appearance. Of course, they are promoting their new movie Ride Along 2 so they took the couple on a "ride along" date. After ditching the Hollywood baggage, Ben and Caila had dinner and a private concert from Amos Lee, one of Ben's favorites.

She totes got the rose.

The second group date got a little weird. Ben wanted to see if science would determine who he should be with. They went through a few tests at The Love Lab to determine who had the strongest connection with Ben. It was Olivia. Who also got the group date rose.

Who everyone also hates.

Yes, Olivia is officially public enemy number one. No one in the house was fond of her antics during the rose ceremony as she continued to steal Ben away, despite already having a rose. In fact, at one point she said, "Ok, I'm done. You guys can now have at it." Um, rude. Lace even confronted her about it, but failed to really make an impact.

In the end, it was Lauren B, or LB, who eliminated herself from the competition. She pulled Ben aside after he offered her a rose at the rose ceremony and told him that the process was not for her. Ben also eliminated Samantha, Jackie and Mandi. We're wondering who else would have gone home had LB stuck around.
