I would but I have much too much fun impersonating dead people. Do me a favour and pour me another drink!
I would but drinking anymore would give me alcohol poisoning Do me a favour and help me get out of my writer's block.
Well, I would, but I'm afraid I'm only authorized to handle spherical writer's objects. Do me a favor and fix my glasses.
I would, but there's honestly not much you can do in a straight jacket. Do me a favor darling and fetch me the TV remote?
I would, but as the song 'Handlebars' tells you: "I can take apart the remote control, and I can almost put it back together." Do me a solid, and solve my procrastination.
I would but I have no idea where pizza lives or how to kill it and properly prepare it. Do me a favour and rewind time so I can get the package I missed.
I would, but the last time I rewinded time Hitler got to power. Do me a favour and help me figure out what eye colour I have.
I would, but I'm so afraid of dogs I freeze up and panic whenever they're around. Do me a favour and show me the true meaning of Christmas.
I would but the true meaning of Christmas has been lost for millennia and I'm not creative enough to come up with a believable lie to tell you. Do me a favour and be my boyfriend.
I would but the last time I tried to admit anything I ended up confessing undying love for popcorn shrimps. Do me a favour and go to the store for me so I don't have to.
