I thought this was particularly humorous:
<object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/Fitxofd7kOA&rel=1"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/Fitxofd7kOA&rel=1" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object>
For people that find the above true for them ... it might not be as funny.
