Apollo–Soyuz: a handshake in orbit
Three languages aboard: Russian, English and 'Oklahomski'

On 17 July 1975 Soyuz and Apollo docked and Leonov shook hands with Stafford. NASA had expected the handshake over the English resort of Bognor Regis; a delay put it over Metz in France. Teasing Stafford's drawl, Leonov said three languages were spoken: Russian, English and 'Oklahomski'.
