First Grade Cubs Fans Make up Song About Jake Arrieta [VIDEO]

If it's one thing I've learned about Cubs fans over the last few weeks is that you start 'em young and they're fans for life.

Meet Mrs. Maciuba's first grade class from Union Ridge Elementary in Hardwood Heights. Like a lot of us, they love Jake Arrieta; so much so that they decided to write a song about him. Arrieta, he's the very besta.

Adorable.

These first graders aren't the only ones paying tribute to Arrieta in a fun and unique way. Click the link below and see the 9-year-old who has the star pitcher's face shaved into the back of his head.

Go Cubs Go.
