Deliberate mistake: Earl attended the "2005 National Daylily Convention." The wording is not accurate, perhaps for purposes of brevity. There is no "National Daylily Society", but there is an "American Daylily Society." Likewise, there is no "National Daylily Convention", but there is a "National Convention for the Daylily Society." (Incidentally, the dates for 2022 are/were July 6 - 9). (00:03:43)
Continuity mistake: Earl shoved the stacks of $100 bills back into the envelope and appeared to put the envelope back into the console with his right hand, but when the camera shifted, Earl was holding the envelope in his left hand with the stacks of $100 bills partially pulled out again. Earl put the envelope of money into the console a second time, but with his left hand. (00:36:05)
Continuity mistake: In the auditorium, there is an elderly man seated in row #2, seat #3 (right to left) followed by an empty seat #4. When Earl moves from Row #3, seat #2 to seat #3, the elderly man should be right in front of Earl, but there are two empty seats and the elderly man is not visible. (01:07:20 - 01:07:45)
Other mistake: When Earl is walking toward his seat in the auditorium's third row at the "Glam Cosmetology Graduation", up to four seats can be seen in rows #2 and #3, but five seated graduates can be seen in row #1. Row #1 is closer to the camera than the other rows, so four or fewer graduates should be visible in row #1, not five. (01:07:20)
