If anybody out there can give me a good pshat in Tosfos פסחים כב: ד"ה ואבר מן החי לבני נח then you are a true scholar and deserve the best shidduch since Yitzchak got Rivka [and if you are married children like Yaakov Avinu]. I anxiously await your reply... I have been troubled by it ALL DAY.

Is the Superbowl over yet? Did Bob Griese throw any touchdown passes? Did Johnny Unitas set any records?

The Tosfos is really bothering me more so please answer that one first.
