Some assorted feats for an iconic classic animated web series on Newgrounds.
A Grunt Rips The Head Off Another Grunt[]

Grunt: 176 px/1.8796 meters (All of the grunts are the same size as Hank who is 6’2”)
Head: 73 px/0.77960681818 meters
The human head pops off between 5000 N and 15000 N, so I’ll use the middle value which is 10000 N.
10000*0.77960681818 is 7796.0681818 joules/7.7960681818 kilojoules, or Street level+
As for the LS given that F=MA...
10000/9.8 is 1020.40816327 kg, or Class 5
Since the grunt ripped the head off with a single hand, doubling the result for the lifting strength using both hands yields 2040.81632654 kg. Pretty much everyone superior to the basic grunt (up)scales from this.
Tricky Burrows Underground[]

Grunt: 185 px/1.8796 meters
Grunt head width (Hole width): 73 px/0.74168 meters
Distance Tricky moved: 380 px/3.8608 meters
Timeframe: 0.12 seconds
Distance Tricky moved in a second: 3.8608/0.12 is 32.1733333333 meters
Given how the hole was at least deep enough for Tricky’s height to fit within it, given how he‘s the same height as Hank, I’ll take it that the hole depth is 1.8796 meters.
Volume: 1.8796*0.74168*32.1733333333 is 44.8516126621 m^3, or 44851612.6621 cm^3
We don’t see any fragments flying out as Tricky dug underground with his sign sticking out, so this must be pulverization.
214.35*44851612.6621 is 9613943174.12 joules/2.297787565516253 tons, or Large Building level
