Dan tells us “Jerry can really hold his Johnny Blue.” 
Amy says: “Just remember to send the e-mail after the GO GO GO GO on WEDNESDAY  Remember Jerry is ALWAYS RED..Do not fall for the Fake Jerry's.” 
I think I’ve got it. We feed Jerry a Jerry can full of Johnny Blue so he will give a Red GO GO GO GO signal to start the drunken ganza. 
If Jerry drinks a Jerry can full of Johnny Walker Red, he will get confused and give a Blue signal, it will be a sober fake ganza and we’ll all waste our emails.
That’s how the rules work, right?
