Alexander Skarsgård and Michael Peña may play cops in their new screwball comedy War on Everyone, but it'll be long time before the real police ask them for any help.
I put them to the test at SXSW to quiz their knowledge of police terms and slang.
Do you know what a "Q-tip" is? How about a "trunk monkey?"
Check out the video above for all the fun.
In War on Everyone, Skarsgård and Peña star as crooked cops who blackmail and intimidate criminals until one proves to be more dangerous than they are.
