While promoting Lone Survivor last week on Conan, Mark Wahlberg shared a hilarious anecdote about the time his youngest son met his Pain & Gain co-star The Rock. Wahlberg explains exactly what happened in the video above, but let’s just say the kid was definitely punching above his weight in this one.

Speaking of Lone Survivor, the movie, which is based on the true story of a Navy SEAL mission in Afghanistan that goes wrong, enjoyed the second biggest January opening on record, making an estimated $38.5 million at the box office. Lone Survivor is directed by Peter Berg, who is currently shooting the pilot Ballers for HBO. Ballers stars both The Rock and Wahlberg, who are also executive producers on the project. The Rock tweeted from the set last week (see below).

In related box office news, The Legend of Hercules, starring Kellan Lutz pulled in $8.6 million on its opening weekend. The second Hercules movie—Hercules: The Thracian Wars—starring The Rock is slated for a July 25 release.
