What would you do?

Sit down and have a glass with him

Congratulate him on recently losing a lot of weight and becoming quite fit

Tell him you're his new dad and ask for an autograph

I feel like a heel for this, I haven't seen many of your films. I loved you in Moneyball and I really want to see War Dogs.

Tell him he was a convincing asshole in Wardogs and that he's a funny guy. Flirt with him and have that glass of juice- then tell him his mom is a lesbian.

So... what's up the HILL?

high-five him

Sharon's got the crazy eye

ask if there is any more orange juice

Tell him I love his movies, and start calling him "Son" just to piss him off, and hope he retorts with "You mother fucker..."
