Pingback Excerpt Getting It Wrong

Hi guys, this has been bugging me for the past few weeks. Suddenly my pingback excerpts have been using a bunch of article titles. I think its from my sidebar’s most popular posts. Here’s an example:

This article, links back to one of my old posts here:

http://www.thetechnoclast.com/2011/05/16/cherry-mobile-orbit-50-off-lauchmay-19/

The excerpt should be something like this:

“It was a hot and sunny Thursday morning when we walked into the SM North Annex building to line up for the Cherry Mobile Orbit 50% Sale event”

But what I get is this:

[…] New 600D Vs. 60D–Which One Is Better?HTC 7 Mozart Review + HTC Goodies ContestCherry Mobile Orbit 50% Off Launch–May 19HTC Desire HD and Desire Z Prices, Release Dates AnnouncedLG Optimus 2X & Black Online Discounts […]

These are a bunch of article titles I have that were popular at the time, and I have a sidebar with popular posts. I think the excerpt is somehow getting them from the popular posts and using it as excerpt. I don’t know how to fix it.

Can someone help me with this one or suggest something? Thanks!
