The one where princess wants to fence and loves taking care of a little boy and the one where kitten lies about a boyfriend.

I think kitten's boyfriend was named George. I was waiting for the last name of Glass.

Those were season 6 episodes.

Betty was tired of not winning anything (she must have a bad memory) and takes up fencing, bound and determined to win a tournament. In a subplot, she also enjoys her babysitting job for a likable six year old. But, alas, on the day of the competition, the boy's aunt calls, and he is leaving town. Tomorrow morning. So, Betty skips the tournament and babysits him, in the Anderson backyard, where she can take sword shots at her brother while the kid watches and eventually falls asleep.

In the other episode, George (not made up, like Mr. Glass lol) and Kathy have eyes for each other, but both are shy. Bud recognizes Kathy is exaggerating her romance for the family; for once, he is kind to her and arranges a surprise-to-Kathy date for them at the town picnic. But not before some pre-picnic tears from Kathy, who is worried that the family will find out about her deception. But George arrives, in sitcom style on cue, just in time, and they are all happily off to enjoy some homemade ice cream at the picnic.
