Take them off

You watch for a minute as the guy looks at the seat of his pants on the window reflection trying to evaluate the damage.

"You'd see it a lot easier if you took them off." You mentally prod him and smile to yourself as he sits down, unlacing his shoes. He does a quick look around, before unbuttoning and slipping off his pants, holding them up to look at the large hole across the arse.

"Dammit, I'm gonna have to go home and change." He mentally curses, preparing to pull the pants back on.
