Last summer, Aaron Collins' family honoured his last wish — they tipped a waitress $500.
A video of their generosity went viral. Strangers, moved by the gesture, started donating to a fund to keep the tipping going.
More than $60,000 poured in from across the country.
Since then, Collins' brother Seth has been dolling out similarly generous tips across the United States. He hopes to eventually give out 100 tips of $500 each, spread out over all 50 states.
So far, he's left 54 tips.
