So, every year we wait til our pumpkins start rotting and then throw them in the back yard for our pigs to eat. Apparently there’s been enough rain in Arizona this year that we now have an actual pumpkin patch growing in the backyard

Dear Dr. Baym,
Hello. I am dog. I would like to do a PhD in your lab. I was told I am already half Lab, so this seems efficient.
I have seen the video of your very big plate where the bacteria evolve across it. It is the best thing I have ever seen that is not a ball. I promise I will not lick it. I have thought hard about this promise and I am fairly sure I can keep it.
My qualifications:
	•	Excellent nose. Can probably sniff out resistance, and definitely sandwiches.
	•	Strong background in fetch, which I understand is most of grad school (papers, reagents, coffee).
	•	Highly motivated by treats, praise, and plasmids.

First panel shows man explaining something. Second panel shows woman asking “well, did it work for them?”. Third panel shows man responding “no, it never does”. Fourth panel shows man continuing “but it might work for us”

Not at all! The flavors-Chocolate

All other terrible things acknowledged and aside… conservatively, 200$ million dollars just poof for no reason
The F-15EX Eagle Il has a reported flyaway cost of approximately $90 million to $97 million per unit as of late 2023, based on production lots
2-4. When fully equipped with advanced systems like the EPAWSS electronic warfare suite, the total cost for a combat-ready aircraft can reach up to $117 million.

Just need to share that J bred an awesome horse that she is going to own/ride forever, and when he was born it was a rule on the farm that year that the horses were named after NASCAR drivers… And it’s kicking the a$$ of many other fancy horses… And his name is “Ricky Bobby” and that’s perfect
