Radio Jerevan is a format of jokes popular in the Sovjet Union
Now, these kind of jokes may be considered somewhat... subversive, but I feel it's necessery to collect these for archival purposes, and cus they are pretty funny. It'd also be interesting to see this kind of joke tailored to our land of Equestria. Let me start with my favorite:

"Radio Yerevan, could mosquitos start a revolution?"
"In theory yes, because the blood of workers flow in their veins."
