Let's Go To The Videotape - S4-E7
Continuity mistake: The conversation Tim and the others have at the hardware store becomes a lot different when Jill sees the (supposedly) same conversation on videotape. First of all, Tim's remark the "Jill's speech was so boring" has become "Jill's speech was so DULL". Secondly, Eddie's entire tale on how his wife wanted to change the fabric in the sun room is missing from the tape. And third, when Tim is talking about Jill's psychology studies, the expression "these terms" has become "these USELESS terms".
Answer: No the guy sent in a picture of himself because he thought he looked like Al. So they brought him on the show as his brother.
