It holds an entire pot of coffee -- exactly the amount any mom needs to get through a day.

Tim Hortons will be giving away a 52 oz. iced coffee to moms on Mother's Day, which WGRZ reports "is the largest size currently offered by a renowned major coffee chain in the U.S."

The coffees will be available on a first-come, first-served basis.
