Well, for some reason, GHWB apologized on this. That part doesn’t look good if you did nothing.
Reading the apology, it may be, via the Bush spokesperson, it may be for telling the dirty joke, so maybe they don’t deny this part and others may have heard it.
Still, why tell a dirty joke at some sort of event like this?
Well, his son, good ol' Dubya, either refused to defend himself or apologized for all the fake allegations from the Dems. The apple does not fall far from the tree.
