My grandfather was wearing latex gloves and had his hands deep in the batter filling a cake pan, laughing and saying he was allergic to the batter.
But it was set-up for a gag because he brought out the baked cake which had the gloves embedded in it.
He then blew hard into the latex gloves to rapidly over-inflate them, causing the cake to erupt, cake chunks blasting the family while he cackled.
Pretty solid bit.
