I'd like to see a nice pre-interview with a hot porn star. Ask the usual questions about their first time with a big cock and about the big ones they've worked with. Get her to show you their size with her hands. Ask about her ideal size for a cock.
Now bring in the tiny guy with underwear still on and just flat out tell her this guy has a really small dick. Would love to see her reaction.
Of course there should be a good reveal with her showing him just how much larger her porn guys have been. For fun, have her do the comparison of his dick to her forearm like they always do in the big dick videos.
