This is an old joke....one liner.... It use to make audiences laugh in the 1950s. I wonder if it translates humorously into czech. Jen jsem sem přiletal a moje ruce jsou skutečně unaveni. I just flew in and my arms are really tired. That makes me think of this question. the dictionary says 'ruka' can mean either 'hand' or 'arm'. How would I say this....I scratched my left arm with my right hand.???? similarly....I am confused by 'noha'
