If that internal filter was never used from the outset, then any woman deciding to marry you would have to first accept you just as you are...but, given that some women want to "fix" us, that might not help too much...
Dilbert needs to meet a woman whose drive to "fix" him is strong enough for her to resist his lack of an internal filter.
Dilbert's words are covering or at least crowding out the painting. Many publishing programs use a textbox frame to insert words into a layout. The "painting" itself may be in a frame larger than what you see, forcing Scott to delete it.
On the other hand, Scott might have moved things around a little. For instance, the way he moves Dilbert's hands up the menu in the second frame so they're not obscured by the flowers. Mebbe hands are more important than art???
Ah, we as men should all take a lesson from Dilbert. For him to so thoroughly give up on women as to blatantly speak his mind whenever he pleases without fear of "rejection", no tendencies to "sugar coat" or otherwise sweeten any issue or discussion... such liberation should be cherished! :-)
