Night of the blue hands..."Arrested Dev" and "How met mother"

TV Arts

Tonight on Arrested Dev: the gal who ran away with the guy who was on
Just Shoot Me and wanted to be a Blue Man had a blue hand mark on the
back of her head and also her breasts (implied)

On the next 1/2 hour block, on How I met your Mother, Alyson Hannigan
comes home from work as a school teatcher and says that a 2nd grader
got to 2nd base with her during finger painting.  Blue hand mark on
her outfit over her breast.

What did I miss?

I'm not sure what the deal was with the CBS show but Arrested
Development was doing a plot with Tobias trying to join the Blue Man
Group all last season, so the blue was a long running joke.
