Tourists have a knack for turning even the simplest trip across town into an obstacle course. Between the crowded sidewalks and endless photo stops, they can certainly test your patience. Just ask Glenn Strange!

According to Gregory William Mank's book It's Alive! The Classic Cinema Saga of Frankenstein, the actor once had quite the run-in with a tourist.

You might remember Strange as the Monster in Abbott and Costello Meet Frankenstein. While shooting the film, he recalled having lunch with fellow actor Ann Blyth, who was also on the lot filming Mr. Peabody and the Mermaid.

Strange was still in his Frankenstein makeup, while Blyth was dressed as a mermaid.

"We were just minding our own business, having our lunch outside a soundstage, when it happened," Strange said. "Like me, Ann had to keep on her makeup until the day's shooting was over. Naturally, she couldn't walk around with her feet covered with a mermaid's body, so they had fixed up a little cart for her to lie in."

Here's a tip for any tourists visiting a movie lot: You're bound to see some unusual sights. But apparently, one visitor wasn't prepared for just how unusual things could get.

"Well, this tourist suddenly came around the corner and saw us," Strange said. "She took one look at the crazy sight of a Monster and mermaid eating lunch together, let out a screech, and hit me in the face with her purse! Then, she ran off screaming bloody murder, leaving me with my lunch all over my face and costume!"

Talk about a monster of a lunch break! Strange may have been used to frightening audiences on screen, but apparently, he wasn't prepared to defend himself against an unsuspecting tourist's handbag.
