Avalanche stars Cale Makar and Devon Toews weren't only losing their minds at the Stanley Cup title parade on Thursday ... they also lost their shirts -- after they stripped during the ceremony!
The hilarious moment was captured on live TV ... when Makar and Toews were celebrating Colorado's huge win on the upper deck of one of the fire trucks in the parade, which was held in downtown Denver.
You can see Toews and Makar were lit (and hot since it's 80 degrees there Thursday) -- and they both took off their championship T-shirts right near Makar's MVP trophy.
