This is a short-form classic.
You probably remember it from Whose Line Is It Anyway? Ryan Stiles was usually a hapless chef, forced to mix and eventually eat disgusting concoctions prepared with the “help” of Colin Mochrie.

To begin, choose four players. Two people stand with their arms clasped behind their backs. The other two thread their arms through the “holes” on either side, then perform a two-person scene as normal. The players in front do all the talking, while their “helping hands” do all the gesturing.
The contrast between what the audience sees (someone scratching their nose, stroking their chin, or twiddling their thumbs for example) and what’s being said is half the fun.
Here’s a great example (sans words) using dogs. Click below to view.
