Whats the best way to get a small shard of glass out of my foot?

I stepped on a very small sliver of broken glass a little bit ago that I missed after a cup broke the other day. Tweezers are not getting it and a needle does not seem to be working to reveal it. (No, I do NOT need tips on how to pick up broken glass, I only missed a small shard which went a much farther distance than expected)
