Is inflatable yak butter as good as regular yak butter?
That’s …quite something.
Or that an inflatable sheep is too obvious? 
And now that I have that out of my system IIRC back when Ren & Stimpy were big someone made an inflatable yak pool toy; a friend actually had one. Again going by memory I would say it was the size of a 4 year old. If your google-fu is strong maybe adding R&S into the search somehow may get you some results.
Looking at the balloons filled with milk in ftg and Peter Morris’s link, I was wondering if yak kumys is a thing.
Darn, I didn’t notice that FTG had already linked it.
How about a hippity-hop yak?
It seems that you may be suffering from (as mentioned on one of those balloons) Silly Yak Disease.
BTW, in case the need comes up, I have sourced an inflatable AK and an inflatable K.
“Ren and Stimpy inflatable yak” got me this.
There are a number of balloons with yaks upon them listed on Cafe Press.
ETA: There are also a number of t-shirts and so on. Here’s one from Amazon.
And I actually had enough cognitive thought to call our friends this AM; they have no memory of where theirs came from but the box did have a R&S tie-in. Their best guess is that they impulsed it while at a Wally-World or Pool City.
Can anyone help me buy a stuffed yak dog toy? This one is out of stock at the places I’ve checked.
I like the Highland cow better, but am concerned about durability. Earlier this week, Pluto chewed through the head of a plush crocodile dog toy in about 45 minutes.
You trying to hijack a yak yak, Jack?
And dat’s the fact!
Unfortunately there’s no yaks on Cebu.
Would you settle for an inflatable Yakko?
Faboo!
Ewe!
Not to speak for Qadgop, but in most cases it is a highly desired, if not crucial, part of the relationship.
OTOH, yaks on zebus have created hybrids.
I like it. The tousled hair and beard makes Zak the Yak look like a very intellectual yak, in an academic sense. You can just picture this yak giving a lecture on Hegelian dialectics, its over-long fur flapping delightfully with each emphatic gesture. Plus the ad says it’s suitable for ages 10 months and up, so I qualify.
