Saiyan Pride appears a lot throughout Dragon Ball Z, and it's usually demonstrated through Vegeta's many impulsive decisions. However, Goku's had his share of pride-driven moments as well.

In the Saiyan Saga, Krillin is seconds away from destroying Vegeta when Goku begs him to stop. While Vegeta eventually becomes a good guy, he's everything but good at that moment, as he had just tried to annihilate Goku and his friends moments before.

Goku has no idea that Vegeta will eventually switch sides, and he doesn't care. Goku wants a rematch with Vegeta. Despite the fact that others may be put in danger because of this, Goku wants Vegeta to be spared.

In the Majin Buu Saga, Goku reveals that Super Saiyan 3 is a transformation that he has long possessed. Yet, he allows his fight with Vegeta to drag on, allowing Babidi to gather enough power to awaken Buu.

Goku claims that he did this to spare Vegeta's pride, but given the way he  punches Vegeta, it can be assumed that he just wanted the rematch.

Later on in the saga, Goku is revived and returns to Earth in order to fight Buu. He then admits that he could have easily defeated Buu in his Super Saiyan 3 form, but didn't do so because he wanted Goten and Trunks to fight the villain.

Then, when Goku and Vegeta face off against Buu in the Supreme World of Kai, Goku comments that he could've defeated Buu when their battle began but held back to give Vegeta a go.

All these instances involve Goku's Saiyan Pride. Perhaps the two Saiyans have more in common than they'd like to admit.
