My boys look a lot like each other (see my previous rant about the "Are they twins" incessant questioning), but not a lot like me-- at least not just at a glance. Twice this week I had someone comment that my husband must be blonde because where else would these kids come from since I am a dark-haired/olive-skinned girl and my boys are blonde-haired and fair-skinned.
Trust me, they're mine...I have about 40 hours of combined labor hours to document it ;)
