In fact, it’s one of my favourites, from Summer of 4 Ft. 2.
What better way to express Lisa’s anger than to have her absolutely stick it to Bart. The almost unnerving reversal of roles is gleeful to watch as Bart is stunned into silence. The grip on his shirt and the way his hair falls back are indicative that he is clearly at her mercy. The fact the she is glowering down at him reinforces the fact that she is in charge.
It’s great to see that Lisa can, on occasion, equal her older brother in terms of menacing behaviour.
Although it’s the subtlety of the scene that makes it so effective. Lisa could have gone off on a rant, shouting and yelling at Bart (and she does in other episodes) however, here, she is much more refined in her approach, which makes it all the more effective as a scene.
The joke of the whole thing is that all of this goes on as Milhouse sits unseen at the other side of the table, completely oblivious to what’s happening right in front of his nose the entire time.
