On the left is Jenny O'Hara and on the right Steven Anthony Lawrence.

Both were frequent guest characters in a lot of 90s shows and movies. Not knowing either of their names at the time, I always assumed she was his mom because of the resemblance.

Am watching through The Drew Carey Show and Frasier at the moment, and they both popped up in each. Finally looked it up to confirm, and, nope, not even slightly related.
