YouTube stars Wesley Chan and Philip Wang caught up with Hanks and director Ron Howard at the premiere of "Inferno" in Florence, Italy this week, where they asked Tom to give a very special performance of his famous rap from "Big."
After a quick Q&A, Wang asked the "Sully" star if he would mind performing. Of course, Tom didn't disappoint, knowing every single word to the memorable movie moment all these years later.
Check out the video above to see Hanks in action (right around the 3:43 mark)!
This isn't the first time the Oscar-winning actor has impressed with lines from past movies -- the 60-year-old teamed up with James Corden back in March where they acted out famous scenes from all of his beloved flicks.
