It's just funny to watch how 160,000 Russian soldiers and 50,000 Donbass militias slowly kick the ass of a million Ukrainians mobilized under arms. Do not take it to heart, Ukraine initially had no chance.
We all have a different sense of humor. I don't laugh when a bigger country with a stronger military force attacks a smaller one. It's a tragedy for both nations but at least Ukrainians are dying defending their land. What are Russians dying for in Ukraine?
If we really have to look for funny events in this war, I find it funny when Russians have to abandon their tanks in the middle of the road because they run out of fuel. It's also funny to see Russian troops driving around Ukraine in a civilian Lada get a grenade drooped on their heads by a drone. It's amusing to watch Russians abandon their friends in the middle of the field and drive away in a truck while those poor guys chase them on foot or top hear those intercepted phone calls where Russian soldiers brag about stealing cars and eating dogs... The war will end but the image of Russian soldier who steals and rapes and shoots himself in the leg to be sent back home will remain forever.
