yeah, i wonder why folks applaud at the end of the anthem also, but that is more because i used to be surprised that everyone acts like the flag code doesn't exist and that you're not supposed to applaud afterwards, but you're also not supposed to use the flag as a bikini, so...
on a side note, i loved the part where emenim took a knee. that was worth stopping my book and unmuting the tv when the s.o. wanted to watch halftime. i love pepsi, and this just made it all the better, even though it can take months to go through a six pack.
