What are some episodes where people spoof being a member of HPD by wearing a uniform which they have gotten at a "costume store" (actually said in one show) or elsewhere? Bobbi and I discussed this, coming up with the following list, are there more?

Guys with uniforms who were not cops:
John Louisiana
For a Million...
Over Fifty, Steal
I'm a Family Crook
30,000 Rooms (a security guard?)
One Born Every Minute (Mossman)
Tsunami
School for Assassins (ugh)

Guys who were cops, might have kept their uniform:
Nightmare in Blue
Rest in Peace

Use of a military uniform (or not a cop):
Yesterday Died
R&R&R
The Ransom
Forty Feet High (did this involve uniforms?)

Pretending to be cops, no uniforms:
My Friend the Enemy
Welcome to our Branch Office

H50 guys pretending to be cops:
Target - A Cop
