Because it seems like the same 10 people are popping up on every show and it’s really disorienting.

Last night the principal from Glee was playing the Indian kid’s dad on Community (at least they didn’t use Ranjit from How I Met Your Mother, I guess.)  Also on Community is Pete Campbell’s wife from Mad Men, except she looks about 15 years younger.  Speaking of Mad Men, Roger Sterling’s child-bride is on that show Flash Forward playing a teenager, I think.  Flash Forward also stars D.A. Carver from Law & Order, Penny from Lost, and, at some point, Charlie from Lost.

I’m sure there are more examples of this but seriously, what’s the deal?
