A drum major leads the Kansas University marching band onto the field prior to kickoff on Saturday, Sept. 5, 2015 at Memorial Stadium.

Saturday is band day at Memorial Stadium, where Kansas University plays Memphis for a 6 p.m. kickoff. Do you suppose the Jayhawks’ marching band will unveil a formation of a Wildcat blowing a layup?

On a more serious matter, if you can’t watch Memphis play KU Saturday and can only make it to one home game this season, make it Nov. 28, aka Thanksgiving weekend, when Kansas State visits. Stay seated to watch at least the beginning of the second half.

Here’s why: Kansas State football fans no doubt already have started plotting to obtain tickets. What if they get their hands on so many that purple outweighs blue in the stands?

That could lead to the low moment in the history of Kansas football, which is saying a mouthful.

Worst moment in the history of Memorial Stadium? Think I’m embellishing? Keep reading.

Try to picture it: At kickoff, half the crowd wears purple. K-State takes a big lead heading into the locker room. Half of KU’s spectators stand up and leave, meaning three-quarters of the remainder of the crowd is purple. And the unthinkable happens.

The K-State band, without its fearless leader, who is back in Manhattan serving his one-game suspension, does it again. Three-quarters of the fans stand up and roar approval.

Think it can’t happen again? Well, did you think it could happen the first time?

Nobody expected Gen. George Washington to lead 2,000-plus men on a Christmas march across the frozen Delaware River to Trenton to attack British-sponsored German mercenaries. That’s why the sneak attack worked so well. And that’s why Beak Attack II could become a reality.

Everyone will expect K-State’s marching band to be on its best behavior in Lawrence.

Kansas fans can’t take the chance of the Purple Phallic Phormation getting cheered in Lawrence.

It’s on every Kansas fan to make sure that the game is sold out by the end of next week.

Tickets to the in-state football contest can be obtained by calling

864-3141. That’s 864-3141. Repeat 10 times after me: 864-3141, 864-3141, 864-3141, 864-3141, 864-3141, 864-3141, 864-3141, 864-3141, 864-3141, 864-3141.

Call today. If you don’t call and the Cat band does it again and gets an ovation for it, don’t say I didn’t warn you. And whatever you do, don’t turn purple with rage or 100 percent of the crowd will be wearing the color.

Thus far, Kansas has ridden the high road in the wake of Band Porn 2015. Sure, KU students and alumni expressed disgust, but what were they supposed to do, swallow hard and take it?
