How To Give Head

When it Italy, on the first day of my tour, the tour guide woman ("Big Momma") was explaining things about the bus we'd be using. She told us there was a bathroom underneath the back set of steps, where the emergency exit was, yada, yada, yada...
But the most intriguing thing she said was about a hammer that they kept on the bus. She told us that we shouldn't worry if we were in the back of the bus and saw a hammer. Its purpose was "not to give each other the head", but it was there in case we needed to break a window.

Some people laughed when she said this; I think more so at the Freudian slip than her gay joke. I smiled, thinking it was amazingly bizarro.
Now...up till this point, I've always assumed that she was using some sort of variation on "hitting on the head". From what I had remembered of Spanish, they don't say, "I hit you on the head with the bat", but "I gave you the head with the bat", or "I gave the bat your head", or something like that...??? They also don't say, "I cut my arm" or "I hit my arm"; they say "I cut myself", as we do, "I cut myself the arm" or "I hit myself the arm", or something like that.

They basically don't use the "my" because it's implied by the reflexive form of the verb, so "I cut my arm" and "I cut the arm (of something/someone else)" has the exact same three words, but with a different conjugation of the verb (either reflexive or not".
SO..."hitting yourself on the head" would be same as "hitting (something) on the head", or, in the case of the Romance languages, using the hammer to "give yourself (someone else) the head". Am I right so far?
Is it possible that she was just applying this sort of logic to the American language? Or could it be that it was a combination of that as well as possibly knowing what "giving head" means? It seems that if she had any idea what "giving head" was in English, though, that she'd be careful to avoid making slip-up's about giving head. Still, when I learned Spanish and Italian, I never rememeber thinking that this "give someone the something" construction could ever cause such a problem. So...what gives?

P.S., off topic, but I am listening to AOL radio, the remix station, and they are playing the Phillip Steir remix of Steppenwolf's "Magic Carpet Ride". Is Steppenwolf the same band who did "Born To Be Wild", or am I confused? Are they a 1-hit-wonder or a 2-hit-wonder?
