Where can I find the web animation (I think that it was in flash
format) from a couple of years ago that had as its theme "X of Love",
where X is something silly.  I kind of remember the animation having a
name like "<Guy's Name> House of Love" (eg. Jose's House of Love) and
there was a shopping trip involved in which he bought things like the
"lettuce of love".

I remember the animation being from a site that had a lot of
animation, but either I haven't found the site or the animation isn't
online anymore.

When I search for "house of love" I get porn or bad fanfic.

I believe the film is "Pierre's Guide To Even More Love," which
involves a shopping trip at the "supermarket of love."

This is actually a sequel to "Pierre's Guide To Love," which involves
eating at the "restaurant of love."

I hope this helps.

In addition to finding the animation that I wanted, juggler-ga also
found related animation and noted the source.  The answer was complete
and speedy!  Thanks!
