Snopes Urban Legend Website has confirmed that if you go to the Excedrin website
And click on the icon, Excedrin will donate $1 American to buy toys for children in poverty. No strings attached.
Get clickin’ kiddoes! 
HEY! Keep this near the top by posting! The kids need it!
OK I’ve done it. (bump)
You know, we could probably drive Excedrin out of business . . . .
Well it is only a $5000 maximum donation, but still, that’s more than I’ve given this year.
This is obviously a plot to give noisy toys to children-- whose parents will then have to buy Excedrin to deal with a headache THIS BIG!
Ok, did my duty and clicked.
But I kept my eyes closed so I didn’t read any Excedrin ads.
I done it.
Done and Done.
I’ve clicked every day for about a week and a half, since WillSantini started his TFT thread. Bookmarked it just above my SDMB bookmark.
I have clickity-click-click-clicked and I have posted the link as an announcement on my board.
I bet they’re at $5000 by now.
