Alyson Hannigan

Where Have I Seen Them Before ?

So we were all very excited to see Alexis Denisof, Wesley on both "Buffy" and "Angel" (not to mention Alyson Hannigan’s husband), as Robin’s smarmy co-anchor on "How I Met Your Mother."

And don’t forget: Denisof and Amy Acker (Fred on "Angel") will be on the season finale of "How I Met Your Mother."
