My dm rolled three nat 20

So my dm rolled to attack my Goliath barbarian half giant and he had disadvantage already and rolled two nat 20 we play with brutal crits so I was like oh no then my bard used silvery barbs and he rolled another nat 20 at that moment the table lost there mind this was my second ever game. I’m loving every moment of it for the people who might be curious we were level 3 and I used stones endurance after it was halfed to 13 and made it do 2 dmg.
