{Ambrose is drawing on a whiteboard}

Ambrose: So, the first sequence is taken as normal, but the second sequence gets reversed. Then we slide the second one over the first...

Ambrose: ...at each point of overlap calculating the sums of the products of all the corresponding items in the two sequences...

Ambrose: ...until we have a new discrete sequence as a result! So... what do you think of that as an idea for a comic?

Audience member: It's a bit convoluted.

**The author writes:**

As explanations of convolution go, this is pretty shoddy, mainly because it hews very closely to a graphical representation of discrete sequences. Still, the joke (such as it is) is also pretty shoddy and I was unwilling to put in much more effort than it deserved.
