5 out of 5 stars. A+. Laughed out loud the entire time. Really hard to commit to the bit any more than they did:
Fallon was so overmatched by Hader. When Fallon was going for potato chips, Hader had no problem going full milkshake all over his face. Just perfect execution. Fallon annoys me a lot these days with his fake laughing and pandering during interviews and such, but this was great, great stuff.
