In celebration of his 40th birthday on Sunday, John Krasinski started a campaign for the non-profit organization Family Reach, that'll see him work with Venmo to help raise money for the families of cancer patients. 

Krasinski reached out to a few of his famous friends for support, and hung a little something over their head to ensure that he can successfully squeeze a sizable donation out of them. For instance, Krasinski threatened to cancel his upcoming appearance on Jimmy Kimmel Live in Brooklyn if Kimmel didn't make a contribution.

As for his friend Chris Evans, Krasinski jokingly played the guilt card by mentioning that it was the least he could do since he "robbed" him of the role of Captain America. 

In an interview with Variety last year, Krasinski recalled  receiving the call informing him that he lost out on the role of Captain America to Evans. When he found out that Evans was their choice, Krasinski fully understood why they went with him, admitting, "Yeah, look at him. He’s Captain America."
