Yo mama is so athletic...

She files her taxes mid-marathon and still finishes first.

Did You Know?

The joke works by piling two totally unrelated feats — running 26.2 miles and finishing your taxes — into one absurdly overachieving mama. Fun fact: the marathon distance (26.2 miles) comes from the 1908 London Olympics, extended so the race could finish in front of the royal box!
