When Capt. Cutshaw places the mud pie on Col. Kane's desk it is whole and intact. In the next shot the mud pie is very noticeably crumbled.
During an imagined planting of the US Flag on the Moon, Kane's voiceover claims that protein molecules would not spontaneously appear before "roughly 10 to the 243rd power billions of years." The word "billions" here is redundant. The number 1 followed by 243 zeroes is equivalent to saying the word "billion" 27 times.
