Not particularly "phunny". You got a play button and start screen down, there was a bit of sketchy animation on both the old man and the attacker. Nice if you could've made some walk cycles/backgrounds/sounds.
You get a star because the old man going down was fluid (and pretty much the best part) and also the shaky arm.
Everything else was poor. To be honest with you, even though it was short and stupid, if you'd put more time into the animation and stuff it may have passed for mildly amusing.
If you make something else, work harder before submitting.
