Trust me, there's a comic point to this.
On his MSNBC show last night, host Brian Williams made the following comment. (I've tried to find a video of it, but can't. So this is just paraphrasing what he said, though I'll put it in quotes) --
"When Sean Spicer tried to make a comparison to investigations into Russia with Russian salad dressing, he was treading on thin iced. Keep in mind that in just 45 days, the world's greatest Sean Spicer impersonator -- Melissa McCarthy -- will be hosting Saturday Night Live. And she has a history on the show of sketches with salad dressing. Like the time her character was in love with Hidden Valley dressing and was on a tasting panel for her favorite product."
And they then showed the last minute of the sketch. And...well, let's just say that someone on his staff has a great memory, and Brian Williams' point is spot on.
Here's the full sketch from 2011. If you just want to see what they showed last night, you can jump to about the 5-minute mark. But the whole thing is pretty darn funny.
Sean Spicer, beware.
