Problem with the 'half-time show' is, in the UK it will be about 01:30 in the morning - I'm long past being a teenager / young-un so pizza then is a no go..
Pasta bol from M&S has just been wolfed.. I like the sound of your beer idea.. though just gone for 6 bottles of Stella..
Being in the UK, I guess my most common Superbowl - ritual - is turning in at half-time & watching the 2nd half in the morning..
