Watch: Grandpa Rossy serves as intern in Bryzzo's latest ad

Business is boomin', so much so that Kris Bryant and Anthony Rizzo needed a veteran intern to help with their fictitious souvenir company.

The Chicago Cubs duo teamed up at the start of 2016 and founded the corporation creatively called Bryzzo Souvenir Co., which praises home runs and baseball success.

Honoring the start of 2017, the first ad included cameos from Addison Russell, Javier Baez, and former catcher David Ross. This time around, just Grandpa Rossy - referred to as David the Intern - shared the spotlight with Rizzo and Bryant.

After the Cubs won their first World Series in 108 years, the sky is the limit for Bryzzo Souvenir Co. Even more so if Ross gets their orders right.
