I think the funniest part was when one of those guys raised his arm. xD
Just some suggestions-
You might wanna add more variety to the characters. They're so similiar it's hard not to mix them up.
Might wanna add a little bit more FBF to the mouth lip syncing. The tweening can be okay if it's not overdone, which it kinda is here.
