Love, Love, Catchball! Urusei Yatsura : Season 4 Episode 8

Ten has ordered a special item from a Galactic Shopping Center: a set of two spheres called 'Love-Love Catchballs.' One ball is for men, the other for women, and when looked into through an eyehole, will show the person who their intended love is.

Ten takes the one for women, and meets up with Lum, Shinobu, Ran, and Sakura. The one for men he leaves back at Ataru's place. Ataru finds it, and tells Mendo about it. The two go to meet at a coffeeshop, which just so happens to be where the girls are.

However, when the girls look into the Catchball, they each see the following:

-Lum sees her old boyfriend, Rei -Ran sees Ataru -Shinobu see's Sakura's fiance, Tsubame -Sakura sees both Ataru and Mendo.

Soon encountering the boys, a fight breaks out, and Ten rushes off to call the shopping center. It turns out they sent him the wrong catchballs by mistake, with the ones he received showing people the person who will make a relationship miserable.
