"Yeah... I mean, there's been signs I suppose, given the stress of the hero life, but I didn't see it coming."
After the reply, he takes a drink from his beer mug, only the extremely observant might note he's using an old showman's trick - a big, obvious motion to pull the eye away from a quick bit of jotting on a napkin, quite able to write, at least a little, without looking.
The final note on a bar napkin, turned to Ollie absently, again, Ralph's eye never straying, says 'not here, play along'
The napkin shortly thereafter disappears forever after being used to blow the world-famous nose.
