chilada my beloved!!! extra olives please. Hold those onions.
north texas taco chain Taco Casa table setting. A wrapped taco on the left, and on the right the chilada. Their copy cat of the 1970s Taco Bell item the enchirito. It's basically a burrito drenched in enchilada sauce and smothered in yellow cheese and topped with black olives. This person has requested raw onions which I do not approve of.

wow, THE paramount plctures?? wow!! L
scammer trying to scam someone who isn't me who has the same name as me. their email address has an l in it instead of an i. plctures, instead of pictures. They're setting me up for a publishing scam. Or trying to.

look at this freakin' weirdo. I was giving him medicine for his ringworm and he just kind of slowly fell over backwards like in a trance. I was giving him nice scritchies. idk. could have also been a fight flight or freeze thing. Poor baby. He was just cleared by the vet yesterday. Ringworm free!

pretty funny to ai-fuck-up a hand for a movie ABOUT hands
old Mad Love movie poster. Top part is text, MAD LOVE starring Peter Lorre, Frances Drake, Colin Clive, Ted Healy and Isabel Jewell.

Suitable only for adults

Bottom part is Peter Lorre holding Frances Drake from behind with a pair of hands in the foreground around them like they're about to get strangled and you're looking at them from the killer's point of view.

just perusing etsy. ah. good. it's a cesspit. That sure doesn't look like Peter Lorre. That guy sure does only have three fingers. >:| neat!!! I love the future!
gross AI slop shirt on etsy for Mad Love, a 1935 movie starring Peter Lorre as a mad doctor. In the movie he's bald and creepy. This guy on this shirt just kinda looks like generic dracul, holding some lady. Also he only has three fingers and it's really prominent. Right in the center of the design on her neck. You can't miss it.

A coworker asked me what my favorite arcade games were and mentally I'm like goddamn how do i explain Logic Pro, the arcade style picross where the plot is about turning a gorilla into a beautiful lady. He was weirded out enough by twinkle star sprites, which is so normal actually.
Screenshot of logic pros' gameplay. Picross logic puzzle game. Looks like you're playing it on a tree stump, there's all the score stuff like in any arcade game. The player character on the left is a little oni kid with green hair and a little red forehead horn. Insert coin to play against me. Please. I'm so lonely.

Been working on this guy all month to try and get him to calm down. It's happening. It was such a scared baby when it got to the store, wouldn't come near us. Now it rushes to greet us when we're there to check on it. I got him to put a foot on my finger. He rubbed his head on me today too.

I feel like I'm losing my mind staring at this
Cricket delivery bag from BugCo. They're in a weird brown bag with that white thread holding it closed like when you buy charcoal briquettes. There's a picture of a cricket and under that it states "the classic cricket experience"

Under that, tilted, and in a font reminiscent of comic sans it describes the crickets as "plump juicy morsels in stay-fresh exoskeletons"

And then under that in tiny lettering "open with care: contents are escape-minded."

The bag is disturbingly greasy.
