[TOMT] Movie or TV scene where two characters have a moment where they put their backs together, lock elbows, and climb up a pair of walls

I don't know where I saw this scene, but here's more details.
- It might be a buddycop relationship between the two characters
- They have a realization together after making eye contact and immediately assume the position
- They put their backs together, then hook elbows
- Then they start climbing up two walls facing each other by just walking up them by pressing into each other's backs
