The only time in the series, through 6 seasons, that at the counter Mort is seated to Teddy's right. In all other episodes he's seated to his left.
The beginning of the intro has been slightly edited starting this season with features of 1) The burger falls into assembly on Bob's hand, 2) Louise steps forward with one foot and extends both her arms in front of everyone from her far right position, 3) Gene plays a dog barking sound effect on his portable keyboard, 4) Jimmy Pesto can be seen in the reflection of the van window standing across the street
No matter how much has been consumed, all beer bottles are shown 2/3 full.
