I think you may be implying that there is a sexual reference in these commercials. I think the goal of the commercials is that you CAN fit something large in your mouth . . . the monster burger, not what you are thinking.
No, the one I saw last night featured a woman. My daughter and I were offended. Please, "not what [I'm] thinking. Just me and a few million of my closest friends. Get real. Another prime example of sex sells.
I saw one with a woman filling her mouth with straws.
