Question

"That's one small step for a man, one giant leap for mankind", was the phrase Purdue alumni Neil Armstrong planned to say as he stepped foot on the moon during the Apollo 11 mission. However, a careful listening of the recording indicates that the phrase he actually uttered is "That's one small step for man, one giant leap for mankind", skipping the "a" before "man" and thus creating a tautology.

Listen for yourself at either of these links:
