How Did Dana Carvey Play George Bush Sr. Next to Will Ferrell's George W. Bush?

Dana Carvey played George Bush Sr. opposite Will Ferrell's George W. Bush in a sketch. To tower over W, Dana wore huge Herman Munster-style shoes and was padded up, while Ferrell played W as his little baby son, flopping onto his lap ("There you are, son"). In a deer-hunting bit, Dana's Bush rattled the antlers and told W to just keep walking into the woods, which Dana calls an Of Mice and Men moment.
