I'd like to expand on my dad's

I'd like to expand on my dad's R2D2 so that it is tall enough to offer snacks-- or hey, maybe just build a C3PO to accompany it... After handing out the beers all night, of course my robot friends will give mandatory breathalyzers to "the guys" on their way out-- with just a hint of stern sass.

Perhaps R2 could hand out chips and salsa while beeping la cucaracha. I hope no one has already thought of this brilliant plan.
