Will Arnett does NOT shirk his father duties!
The Arrested Development star was spotted at the park playing with his two young sons Archie & Abel.
Will was seeing riding a toy horse, piggybacking Archie and spinning around Abel. All in a day's work for him!
They did everything except a trip to the moon, and that could soon be next!
And knowing this dad we wouldn't doubt it!!
