Actually, I majored in marketing and I have a bachelor of science.

The line plays on the contrast between Wanda Sykes’s public persona as a comedian and the unexpectedly conventional, “serious” credential she claims: a marketing major and a Bachelor of Science. Delivered as a deadpan correction (“Actually…”), it functions as a status-reversal joke—undercutting assumptions that entertainers are uneducated or that comedy is a fallback for people without formal training. The specificity of “marketing” and “bachelor of science” adds comic precision and implies she could have pursued a corporate path, sharpening the sense that comedy is a chosen vocation rather than an accident.
