There’s a common phrase from a popular song about Gagarin:
Он сказал: «Поехали!»
Он взмахнул рукой.
“He said ‘Let’s Go!’
and waved his hand.”
Naturally, Russians being who they are, there are many parody versions; my favorite is “Он сказал: «Поехали!» / и запил водой.” (He said Let’s Go! and drank a glass of water.)
