How to surprise my boyfriend.

Hey everyone! Today was just a generally stressful day for my boyfriend, (When he picked me up for school, he backed into my stepfather a truck, scratched the driver side door and broke his own truck's taillight.) so he's been stressed out and kind of angry today. Which kills me to see him unhappy 😞 So, I was wondering what I could do to lighten the mood? How can I surprise him? I'm open to all ideas! I just wanna cheer him up. Luckily, my stepdad wasn't mad about it and no one is angry at him. It's just embarrassing I guess.
