How about a trade off debate deal?

Personally I would rather debate someone who is on drugs than someone who isn't - because the person on drugs isn’t going to function as well. Biden should call Trump’s bluff and say OK we will both take a drug test then see how long it takes Trump to come up with another excuse. After that excuse Biden should have a press conference and say to the reporters – Trump keeps making up excuses not to debate me – why do you think that is? Then Biden could do a chicken dance while chanting – buck buck buck buck buck. Cheers!
