Glove at First Sight is the first segment of 10th aired and 11st produced episode in season 3 of Dexter's Laboratory, which first aired on June 28, 2002. This episode features Mom and Dad from when they met for the very first time.
Mom and Dad have a flashback all the way back to 1984 when they first met.
The title of this episode is a pun on the phrase "Love at first sight" which is a term used when two people fall in love with each other when they first meet.
It was revealed in this episode that whenever Mom kissed Dad, she puts her glove in the way. However in episodes such as Chubby Cheese, Road Rash, and Streaky Clean, they have been seen kissing without using the glove, implying that Mom may be a germaphobe.
