This is a 14-second Czech voice clip built around Mgfitman calling Havlis, capped with the exasperated line aimed at Havlis. The delivery feels incredulous and teasing, like a friend who cannot believe what he just heard, which gives the whole exchange a playful, caught-off-guard energy that works as a reaction.
